摘要
多目标鉴别是雷达信号处理中迫切需要解决的技术难题。针对Chirp脉冲雷达体制及其相参积累处理的原理和特点,利用多个目标的多普勒谱分布特性,提出了应用CLEAN算法的多普勒谱旁瓣抑制技术实现多目标鉴别。仿真结果表明了这种技术的有效性,且在信噪比较低的情况下仍然非常稳健。
Multiple target distinguishing is one of the most urgent and difficult technical problems in radar signal processing. The coherent accumulation procedure of chirp pulse radar system is discussed, and a technique of multiple target distinguishing with side-lobe suppression of Doppler spectrum based on CLEAN algorithm is developed. The simulation results show the validity of the technique and the robust performance with low Signal-to-Noise Ratio.
