The active amplitude-phase control assembly comprises a program-control phase shifter and a program control attenuator electrically connected with each other successively. The active rapid amplitude-phase control system provided by the utility model controls relative amplitude and phase by the active amplitude-phase control assembly, and can control the relative amplitude and phase of triple radiation signals.
Description
Technical field
The utility model relates to a kind of active quick width of cloth phase control system.
Background technology
The radio frequency simulation system utilizes tlv triple aerial array guinea pig target echo, magnitude-phase characteristics by smart bit machine control control signal, because the control parameter of array-fed system may will change in each emulation cycle, if system works is under the frequency agility mode, then in an emulation cycle, control word may repeatedly change, and passage calculates in real time, and the mode of control output in real time can't realize at all.
The utility model content
Primary and foremost purpose of the present utility model is to provide a kind of can realize that concrete scheme of the present utility model is as follows to the active quick width of cloth of the control of tlv triple radiation signal relative amplitude and phase place control system mutually:
A kind of active quick width of cloth phase control system, described active quick width of cloth phase control system comprises the tlv triple aerial array, described tlv triple aerial array is electrically connected with active width of cloth phase control assembly respectively, and described active width of cloth phase control assembly comprises program control phase shifter and the programmable attenuator that is electrically connected successively.
Preferably, also comprise linear power amplifier, described linear power amplifier is electrically connected with the output of described active width of cloth phase control assembly.
The active quick width of cloth phase control system that the utility model provides can realize the control to tlv triple radiation signal relative amplitude and phase place by the control of active width of cloth phase control assembly to relative amplitude and phase place.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 controls the branch road schematic diagram mutually for the utility model embodiment system width of cloth.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment
As shown in Figure 1, a kind of active quick width of cloth phase control system, described active quick width of cloth phase control system comprises the tlv triple aerial array, three road signals of target echo are delivered to three radiating antennas of any tlv triple aerial array correspondence by switch matrix 1, form three width of cloth and control branch road mutually, described tlv triple aerial array is electrically connected with active width of cloth phase control assembly 2 respectively, described active width of cloth phase control assembly 2 comprises program control phase shifter 21 and the programmable attenuator 22 that is electrically connected successively, the relative phase of program control phase shifter 21 these branch roads of control changes, the relative amplitude of programmable attenuator 22 these branch roads of control changes, with control desired relative phase and the amplitude of assurance system to tlv triple aerial array internal object position, the control figure amount of program control device is that software is sent here by computer and interface.
As the improvement of above-described embodiment scheme, also comprise linear power amplifier 3, described linear power amplifier 3 is electrically connected with the output of described active width of cloth phase control assembly 2, and linear power amplifier 3 is the compensation to power loss in the branch road.This assembly is the core of system's smart position control, and amplitude and phase control have strict requirement, mainly shows the stability of single branch road amplitude, phase place, the power modulation characteristic, the width of cloth/phase iteration precision, and the consistency of the width of cloth/phase between each target branch road, aspects such as the consistency of power modulation.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
