| 摘 要： | 针对大型相控阵雷达工作在宽带、宽角扫描的情况下,瞬时信号带宽受孔径度越时间限制的问题,从理论上分析了影响相控阵雷达线瞬时带宽提高的因素和接收通道幅相误差对系统性能的影响,提出了采用射频延迟和视频延迟方法提高相控阵天线瞬时带宽的两种技术途径。并给出在微波暗室里进行的相控阵试验雷达工作在宽带角电扫描情况下成像试验的部分结果,验证了理论分析的正确性。

| Abstract: | When large phased array radars work in wideband wide scan conditions instantaneous bandwidth of signal is limited by the size of aperture. The factors of banwidth limitation and the effects of receive channels phase and amplitude errors on radar are analyzed in theory. Two methods for improving bandwidth of phased array by adopting RF and IF time delays are presented. Test Results of high-range resolution images from a phased array radar in microwave anechoic room are given, which demonstrate the validity of the analysis. |
