摘要
采用相参干扰方法干扰脉冲压缩雷达是目前实现突防的重要手段,它会严重影响雷达检测目标的性能。针对此问题,提出利用EASI盲分离算法抗相参干扰,该方法能提升雷达在复杂相参干扰环境中对目标的检测能力。仿真实验表明,EASI盲分离算法有效降低了间歇采样干扰对脉冲压缩雷达探测性能的影响,具有良好的应用前景。
Using coherent jamming method to jam pulse compression radar is an important means to achieve penetration, which will seriously affect the performance of radar detection target. Aiming at this problem, an EASI blind separation algorithm is proposed to resist coherent jamming. This method can improve the detection ability of radar in complex coherent jamming environment. The simulation results show that EASI blind separation algorithm can effectively reduce the impact of intermittent sampling interference on the detection performance of pulse compression radar, and has good application prospects.
