Description
Technical field
The present invention relates to a kind of countermeasure test method, radar network and networking jammer in more particularly to a kind of laboratory
Countermeasure test device and method, belongs to countermeasure test technical field.
Background technology
Radar is " radio detection and range finding(Radio Detection And Ranging)" abbreviation and transliteration.
Radar is used to detect and position reflection object, and from title, the most basic function of radar is to find target and measure its distance,
But the development of the growth and technology with demand, radar can also measure target angular position, radial velocity, echo signal intensity etc.
Parameter, realizes the tracking to target, and can obtain target RCS by analytical calculation(Radar Cross Section, radar
Sectional area), target polarization characteristic, the information such as target fine motion feature.Detected and processed using radar opposite/body target, can
To carry out SAR/ISAR imagings, scene or the mapping operations in space, and then realize identification, the acquisition of spatial information to target.
Therefore, radar plays an important role in military, civil area.
The general principle of radar work is the radiofrequency signal for producing emitter by aerial radiation to space, transmission signal
Scattered after being irradiated to target, radar receives target echo signal using reception antenna, and realizes in receivers to target
Detection and measurement.The operation principle of above radar is as shown in figure 1, in Fig. 1, radar emission and reception signal have used two antennas
Realize, in practical application, many radar emissions and reception signal share same antenna.Reach the signal reflex energy of radar not
Only showing the presence of target, and, by comparing the target echo signal for receiving and radar original transmitted signal, can also determine
Target location simultaneously obtains other information relevant with target.Radar can be in different distance ranges, different meteorologies and weather
Under the conditions of work, these characteristics do not have other equipment to realize.
In practical application, covering same spatial domain using the multi-section radar of identical or different type, combine is carried out to target
Detection, it is possible to increase target detection capabilities, reduces false-alarm probability and false dismissal probability;By the result of detection of comprehensive multi-section radar,
Radar measurement accuracy can be improved.Therefore, for emphasis spatial domain, usually using the work of multi-section radar network composite.
In order to resist the detection of radar, detected target is screened, active interference signal is produced usually using jammer, realized
Deception or compacting to radar, so as to influence normal detection of the radar to target.The spatial relationship of jammer and protected target
There are built-in, accompanying flying formula and support formula.Wherein, built-in jammer is installed on protected target, is existed with protected target
One is formed in structure;Accompanying flying formula jammer, by shedding or towing mode discharges, one is spatially kept with protected target
Fixed relative position relation, generally requires guarantee jammer and is located between radar and protected target, to obtain preferable interference
Effect;Support formula jammer, is spatially distributed with protected target and relatively opens, and does not have strict relative position requirement, supports formula
Jammer realizes interference by the secondary lobe Injection Signal of radar.The interfering bodies of jammer is formed with pressing type interference, Deceiving interference
Deng.Pressing type interference uses coherent or non-coherent signal, neutralizing target echo-signal so that radar cannot be carried out effectively to target
Detection and measurement;Deceiving interference is used for simulated target echo-signal, according to the difference of Tactical Application, destination number, target
Distribution distance, Target Signal Strength, the target characteristics of motion can set so that radar can also be seen in addition to detecting real goal
To a large amount of virtual decoy signals, the cell processing such as Radar Signal Processing, data processing, target identification load is caused to increase,
So as to influence the normal working performance of radar.
During actual interference machine and radar electronic warfare, with the demand that many jammers of configuration work simultaneously.If having many
Portion's radar is covered and need to screen region simultaneously, and multi-section radar operating frequency difference is larger, and separate unit jammer is difficult to multi-section radar
Implement interference simultaneously, it is necessary to configure multi-section jammer;When needing jammer to carry out investigations radar, especially realize surveying radar
Xiang Shi, single jammer is limited due to size, it is difficult to install investigation reception antenna, can be cooperated using many jammers
Mode, realizes the measurement to Radar emitter;The interference signal of deception jammer enters from radar antenna main lobe, single deception
The false target that formula jammer is produced can only be on the ray determined as origin and jammer position with radar, and this is for deception
Formula interference is unfavorable, can be cooperated in many jammers of space configuration, while the false target echo-signal of coherent is produced,
By controlling the power and phase of each jammer radiation signal, realize reaching equivalent composite signal the control of radar angular, energy
Enough fidelitys for further improving simulated target.Therefore, in actual applications, jammer networking application progressively launches.
, it is necessary to carry out substantial amounts of countermeasure test in jammer development, test, type-approval process, can be with by real winged mode
Realistic simulation antagonistic process, obtains more intuitively test effect, but have that confidentiality is poor, experiment expense greatly, tissue difficulty
The shortcomings of, the field trial for especially carrying out networking jammer is extremely difficult.Therefore, it can consider to carry out phase in microwave dark room
The countermeasure test of pass, many radars of reproduction space and the confrontation scene of many jammers, reach the purpose that part replaces field trial.
Carry out networking jammer and radar network countermeasure test, the laying mode such as Fig. 2 for taking at present in microwave dark room
It is shown.
In Fig. 2, multi-section radar is laid in the side of microwave dark room.Each radar is visited according to its intrinsic working method, transmitting
Signal is surveyed, and receives target echo signal, target detection and subsequent treatment are carried out, with the real work situation of guinea pig.Examination
During testing, each radar record its result of detection data to target.With same experiment situation, increase many jammers and participate in
Experiment, and jammer running parameter and combination are set, carry out the interference test of varying strength, it is separately recorded in thunder under different condition
Up to detection data.It is dry to target acquisition ability and the difference of measurement error, assessment under different confrontation situation by comparing radar
The validity disturbed.In microwave dark room, target and jammer are tried in the offside cloth establishing of radar.It is used to produce and thunder with examination target
Up to the corresponding target echo signal of transmission signal, jammer adds whole experiment as test assessment object with physical form
System.
However, above test method principle is feasible, but it is constrained to the factors such as darkroom size, it is difficult to outside fully equivalent simulation
Field experimental condition.Equivalent simulation requirement reaches the target echo signal and interference signal of each portion's radar in power, arrival time, many
The aspects such as general Le frequency, angle of arrival are consistent with the reception signal under actual confrontation situation.
