摘要
利用外辐射源(如调频广播、电视、GPS等的发射信号)的无源雷达探测技术一直是国内外研究的热点。在目标检测上,直达波信号的干扰不但对通道的动态范围提出了极高的要求,同时对微弱目标回波的检测构成了限制。文中利用二元阵的方法对直达波的干扰进行抑制,并对其对消性能进行了仿真分析和研究。
The technologies of the passive radar based on noncooperative illuminator have interested us greatly. To target detect, the interference of direct signal requires rigorously dynamic scope of channel, also restricts detection of weak signal. The direct signals is suppressed by way of two arrays, and the result of simulation is given.
