| 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。

| Abstract: | Passive radar detection technology based on noncooperative illuminators including FM radio broadcast, TV and GPS has been a hot area of research home and abroad. Interference of direct wave not only imposes extremely high requirements on the dynamic range of channels, bat also constitutes restrictions on detection of weak target echo signals during target detection. This paper uses a two-element array method to suppress the interference of direct waves and its direct wave canceling performance is simulated and analyzed. |
