摘要
机载远程监视雷达系统是一个远程的全天候广域监视传感器。通过对雷达系统性能要求的分析,具体提出了一种FH-DS扩谱连续波雷达体制与方案,采用直升机做空中平台和采用连续波跳频加直接序列扩频的"寂静"雷达体制,同时采用PD/MTI信号处理加波束压缩的准成像处理实现多种功能的雷达方案。针对此方案,进行了信号设计和系统参数及信号处理方案选择。同时还为解决CW雷达收发隔离问题和采用单天线收发提供了解决方案。
The airborne remote surveillance radar system is a remote all-weather and wide-area monitoring sensor.By analyzing the performance requirements of a radar system,this paper puts forward continuous wave of FH-DS spread spectrum radar system and solution. The multifunction radar scheme is implemented by using helicopters as aerial platform, continuous wave frequency hopping“silence” of direct sequence spread spectrum radar system and PD/MTI signal processing and compression of quasi imaging processing. Aiming at this scheme,the signal design and system parameters and signal processing scheme are selected.At the same time the solution is provided for CW radar transceiver isolation and single antenna transceiver.
