摘要
针对相干频率分集阵列雷达距离/时间-角度依赖的信号收、发处理问题,提出一种基于角度依赖匹配滤波的频率分集阵雷达收发联合多波束设计方法。该方法可以同时实现等效发射数字波束形成和信号脉冲压缩匹配处理。且不同空间角度的雷达回波信号可以独立进行处理,通过联合接收数字波束形成技术,可以同时进行收发联合波束形成,实现同时多波束广域宽角覆盖,满足雷达广域搜索任务的需要。仿真实验证明了所提方法的有效性。
Focused on the range/time-angle-dependent signal transceiver and processing issue with the coherent frequency diverse array(FDA)radar,an FDA radar transceiver joint multi-beam design method based on angle-dependent matched filter(ADMF)is proposed.This method can realize equivalent transmit digital beamforming and signal pulse compression matching processing at the same time.Echo signals from different spatial angles can be processed in parallels.Combining with the joint receiving digital beamforming technology,it is possible to implement joint transceiver beamforming simultaneously to realize the simultaneous wide-field wide-angle coverage of multi-beam,and meet the requirement of radar wide-field search task.Simulation examples demonstrate the effectiveness of the proposed method.
