为了解决超宽带信号源的无源定位问题,运用能量相关方法计算天线波瓣,对宽带Ch irp信号作用于阵列天线的波瓣图进行了计算与分析,提出了分类相位控制形成宽带接收波束的一般结构和实现途径。讨论了通过信号带宽提高角度脉压分辨率的一般经验准则。

The receiver for passive location must process a large bandwidth signal in search of the Ultra Wideband radar.So the receive array pattern is simulated and analyzed for wideband Chirp waveform using energy correlation method.And a phase steered array system with three phase codes for Chirp waveform is described,and its feasibility in engineering is discussed.An empirical criterion on improvement of angle resolution by pulse compression is also discussed.
