中文摘要：
主要研究了基于非合作雷达辐射源的非相参体制无源雷达目标检测问题。对目标回波通道中的直达波干扰,利用一种基于三元传感器对消的方法来进行抑制。然后采用周期间相关检测的处理方法对目标进行检测。仿真分析表明,该方法在辐射源信号未知的情况下,能够有效抑制目标回波通道中的直达波干扰,得到优于传统的确知信号的相关检测性能。
英文摘要：
In this paper,the problem of target detection in passive radar is researched chiefly based on non-cooperation radar illuminator. In order to suppress the direct-path interference,the cancellation method is used based on a three-sensor array. Then, the inter-period correlation processing method for target detection is proposed. The simulation results show that this method can effectively suppress the direct-path interference and get better detection performance than conventional correlation processing when the illumination source is unknown.
