摘要
为了对雷达接收机进行通道校准并进一步检验雷达系统设备的可靠性与算法的准确性,提出了全数字高频雷达应答器。分析了现有高频雷达应答器的问题,解决了雷达接收机通道的相位校准和模拟目标运动速度的难题,介绍了全数字高频雷达应答器的硬件结构与程序设计。采用全数字处理与控制模式,体积小,易便携,很好地实现了接收机通道校准和雷达系统设备与算法的检验。
In order to carry out the channel calibration of radar receiver and test the reliability of radar equipment and the accuracy of the algorithm further,a digital high-frequency radar transponder is proposed.This paper analyzes the problems of the existing high frequency radar transponder,solves the problem of phase calibration of receiver channel and the simulation of target velocity,and introduces the hardware structure and the program design of digital high frequency radar transponder.The digital highfrequency radar transponder uses the digital processing and controlling mode,having small volume,being easily portable,and realizing the channel calibration of radar receiver and the test of radar system and algorithm.
