Problems solved by technology
For the detection performance verification of multiple targets in the main beam, it is necessary to use the relative correlation trajectory information of each target and the targets in the process of detection and resolution, so the performance test needs to adopt continuous and dynamic testing methods, which is very important for the detection and resolution process. RF detection system laboratory environment construction, scene simulation, target simulation, position simulation, synchronization between detection systems, test time delay, and scalability put forward high requirements. The test error caused by asynchrony or inconsistent coordination cannot truly reflect the performance of the new method for multi-target resolution in the main beam, which restricts the verification of the new method and the quantitative evaluation of product capability upgrades

The embodiment of the invention provides a main beam multi-target angle resolution test system and test method. The system comprises a system control machine, a radio frequency detection system, a multi-target simulation antenna, a target position simulation support and a time synchronization reference communication module. Wherein the system control machine is used for controlling each module of the system and generating a time synchronization instruction; the radio frequency detection system is used for transmitting a radio frequency signal, receiving an echo signal fed back by the target simulation antenna and carrying out multi-target resolution; the multi-target analog antenna is used for feeding back a multi-target echo signal; the target position simulation bracket is used for moving the target simulation antenna to a specified position; and the time synchronization reference communication module is used for realizing time synchronization among the modules of the system, so that the multi-target resolution performance at different angles can be quantitatively evaluated, and the performance test effect of multi-target resolution in a main beam can be effectively improved.
