摘要 针对弹载宽带相控阵单脉冲测角雷达体制,根据海面上具有一定高度的舰船目标的距离-高度耦合效应、多普勒-高度耦合效应,提出了一种基于通道级空时自适应处理(Space Time Adaptive Processing,STAP)的高度目标检测新方法。该方法在和、差通道距离-多普勒二维成像的基础上,采用自适应对消技术进行杂波抑制,并通过数字方式形成修正的和、差通道。在修正的和通道上进行目标检测,利用修正的和、差通道之间的单脉冲比值测量目标的角度。理论分析及仿真结果表明:该方法在抑制杂波、检测目标的同时,能抑制移位角闪烁、有效改善高度目标的检测性能,且运算量低易于实现。 A new method of lofty target detection which based on channel-level STAP was proposed for missile-borne wideband mono-pulse phased-array radar. The idea of our method is to analyze the range-height and Doppler-height coupling effect of lofty target on sea plane. It carries on range-Doppler imaging of sum channel and delta channel first. Then,the adaptive cancellation technique is used to suppress the clutter. And the modified sum channel and delta channel are formed by digital processing. Finally,the target detection and target angle measurement are carried out by using the modified sum channel and delta channel. Theoretical analysis and simulation results show that the presented method can suppress clutter and improve the performance of lofty target detection effectively. Besides,it has low computational complexity.
