Combined radio frequency signal waveform main target identification and performance test method and device

Abstract

The embodiment of the invention provides a combined radio frequency signal waveform main target identification and performance test method, and the method comprises the steps: constructing a detection target scene, and setting the target number, target distance, target speed and target angle information of the detection scene; receiving synchronous electromagnetic signals emitted by a plurality of targets, performing target identification, and outputting first target distance, first target speed and first target angle information of a main target; after the target distance information is changed, target identification is carried out, and a second target distance, a second target speed and second target angle information of the main target are output; and comparing the second target distance, the second target speed and the second target angle information with the target distance, the target speed and the target angle. In this way, the motion state in the same direction can be simulated, and the effective detection performance of the detection method or the detection device on the main target in the main target recognition and motion state can be tested.

Aiming at the performance verification and evaluation of main target identification and multiple secondary target suppression in cluster multi-target, the current infield hardware-in-the-loop environment performance test method is mainly a special design method, which is customized according to specific scenarios, and the test complexity is high Practical problems such as many test equipment and large target differences cannot guarantee high-precision synchronization between test equipment, complex and changeable scenes, and targets of different shapes. At the same time, the process design and operation of customized special methods lead to long system test cycles, The problems of large time redundancy and poor scalability can easily cause test errors caused by out-of-sync devices and uncoordinated test operations, which cannot truly reflect the real performance of target recognition
