Detailed Description
In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The principle of the idea of the invention is as follows: electromagnetic target behavior is defined as the sum of all the responses of the electromagnetic target to the battlefield situation and electromagnetic environment, such as internal radiation source task assignment and external signal radiation.
The execution of which behavior by the electromagnetic target needs to be determined according to the battlefield situation, the electromagnetic environment and the target task, and the electromagnetic target behavior to be executed is specifically implemented by a radiation source carried by the electromagnetic target; each radiation source carried by the electromagnetic target can realize different functions, and the different functions are combined under the overall allocation of the target so as to realize the behavior of the electromagnetic target; different functions are realized by various electromagnetic radiation sources carried by electromagnetic targets emitting electromagnetic signals; thus, the electromagnetic target behavior may ultimately be characterized by signal variations of different radiation sources in the electromagnetic environment. Therefore, if non-cooperative electromagnetic target behaviors need to be obtained, the above process is reversely analyzed, from the perspective of reconnaissance, an electronic reconnaissance system is used for reconnaissance of the electromagnetic environment, and the behaviors of the electromagnetic targets are obtained by capturing signal changes of the electromagnetic environment and gradually carrying out reverse deduction.
The invention provides a behavior hierarchy model of an electromagnetic target, which can be established by adopting the following modes:
the first step is as follows: and establishing an electromagnetic radiation source hierarchical model.
The multifunctional radar radiation source level model can be divided into three levels, namely a functional layer, a task layer and a waveform layer, as shown in fig. 2:
functional layer: set of radar functions F ═ { F) for a multifunction radar implementation1,F2,…,FMRelative between various functionsIndependently;
and (4) task layer: each function is decomposed into a series of tasks, and the parallel execution of a plurality of functions is realized in a time division multiplexing mode;
a wave-shaped layer: the waveform unit omega is composed of a finite number of pulses arranged according to a fixed sequence and is a basic component of a signal, and each radar task is mapped into one waveform unit or a combination of a plurality of waveform units. All waveform units form a set and are stored in a waveform library of the radar.
Each waveform unit omegaiCan be represented by a set PTN, and contains 3 pieces of description information

the parameter values are descriptions of interval types, where xV,xURespectively as follows: a lower parameter value limit and an upper parameter value limit;

Has different meanings; for example, 0 represents no modulation. Taking the conventional pulse description words PRI, CF, PW as an example, the modulation type of each parameter can be expressed as: PRI: 1-fixed, 2-staggered, 3-group-changed, 4-jittered and 5-sliding; CF: 1-fixed, 2-agile, 3-group-variable, 4-jump; PW: 1-fixed, 2-multiple pulse width combination, 3-dithered.
Figure BDA0003066382600000073
Represents the number of pulses of a pulse sequence in which all parameters maintain their respective modulation patterns.
The second step is that: and establishing an electromagnetic target behavior hierarchical model.
Based on the electromagnetic radiation source hierarchical model in FIG. 2, an electromagnetic target behavior hierarchical model is designed, and the model structure is shown in FIG. 1. The target behavior layer and the radiation source function layer establish a macroscopic corresponding relation between the electromagnetic target behavior and the radiation source function from a behavior layer; the mission planning layer and the signal parameter layer are used for specifically analyzing the electromagnetic target radiation source signal from the signal layer.
For each electromagnetic target, establishing an electromagnetic target behavior level model corresponding to the electromagnetic target; the electromagnetic target behavior hierarchical model is a five-layer model and comprises the following components in the top-down direction: the system comprises a target behavior layer B, a radiation source functional layer F, a radiation source layer E, a task planning layer and a signal parameter layer;
a target behavior layer B, which is a set of behaviors that an electromagnetic target can execute,expressed as: behavior set B ═ B1,B2,…,BNIn which B1,B2,…,BNRepresent the 1 st, 2 nd, nth behaviors that the electromagnetic target can perform, respectively; each action is independent;
specifically, the electromagnetic target behavior is a highly abstract representation of the radiation source signal, and each behavior B of the electromagnetic targeti(i ═ 1,2, …, N) the functions achievable by the radiation source combine, all containing abundant electromagnetic radiation source information. For example, the behavior of ballistic missile defense of a Zeus shield ship needs AN AN/SPY-1 radar pair carried by the ship to perform multiple functions of searching, target tracking, missile guidance and the like, and each function needs to design a task sequence and a waveform unit according to airspace division and target conditions, so that the behavior is very complex in signal level.
The radiation source functional layer F, which is a functional set that can be realized by all radiation sources mounted for electromagnetic targets, is expressed as: radiation source function set F ═ { F ═ F1,F2,…,FMIn which F1,F2,…,FMThe system respectively represents the 1 st function, the 2 nd function and the Mth function which can be realized by all radiation sources carried by an electromagnetic target; wherein, the behavior set B ═ { B ═ B1,B2,…,BNEach action in F, corresponding to a radiation source function set F ═ F1,F2,…,FM1 or more functions of (1) };
radiation source layer E, a collection of all radiation sources carried by the electromagnetic target, represented as: radiation source set E ═ E1,…,EK} (K is more than or equal to 1); wherein E is1,…,EKThe device comprises a 1 st radiation source, a 2 nd radiation source and a Kth radiation source which are carried by an electromagnetic target respectively; the radiation source set consists of different types of radiation sources, such as radar, communication, navigation and the like, and the number of elements of the radiation source set is more than or equal to 1.
Wherein: the radiation source function set is a function which can be realized by all radiation sources of the electromagnetic target, and different electromagnetic target behaviors are realized through the combination of elements in the radiation source function set;
it should be noted that the electromagnetic target is for rationalizationSelf resources are configured, redundant design is generally not performed on the radiation source function design, and from a macroscopic perspective, a plurality of radiation sources can have the same function, such as a function concept of searching and guidance; if further refined, the specific functions performed by the radiation sources with the same function are different, such as that the aircraft carrier is equipped with multiple search radars, but they perform different area search tasks, such as medium and long range searches, marine target searches and aerial target searches; and moreover, as a plurality of guidance radars are equipped, the guidance function can be realized, but each radar respectively realizes the guidance function of different weapon systems. Here, the radiation source function set F ═ { F ═ is set1,F2,…,FMThe elements of the radiation source set E ═ E is a more specific function1,…,EKAnd radiation source function set F ═ F1,F2,…,FMThere is an explicit mapping relationship for the elements of: radiation source function set F ═ { F ═ F1,F2,…,FMEach function of (E) is only connected with a radiation source set E ═ E1,…,EKOnly one radiation source in the unit corresponds to the other radiation source; radiation source set E ═ E1,…,EKEach radiation source in (F) is associated with a functional set of radiation sources F ═ F1,F2,…,FM1 or more of the functions correspond; namely: each function is performed by a unique radiation source, and each radiation source can perform 1 or more functions;
the multi-functionalization of the radiation source is a development trend in the future, particularly, the integration of radar functions is realized through technologies such as phased arrays and the like of the radar radiation source, and the multifunctional radar is widely applied. For example, the AN/SPY-3 and AN/SPY-4 radars of the latest American 'Ford' level aircraft carrier equipment integrate the functions of a plurality of radars such as the 'Nimidz' level aircraft carrier AN/SPS-48E, AN/SPS-49V, AN/SPN-43, AN/SPS-67 and MK23 TAS.
And the task planning layer corresponds to the task layer of the multifunctional radar hierarchical model, and generates a set of task lists of corresponding functions for each radiation source in the radiation source layer E according to the functions distributed by the electromagnetic targets, wherein the set is expressed as: task set
Figure BDA0003066382600000091
