| 摘 要： | 介绍了声表面波器件在雷达对抗技术中的应用。以声表面波滤波器组为核心的信道化接收机，可以实现对雷达信号的宽频的信道化接收和１００％的截获概率。以声表面波延迟线为核心的距离欺骗、多重回答欺骗、噪声欺骗技术是对雷达信号的综合干扰手段之一。在对雷达的低空突防技术中，以ＳＡＷ色散线为核心构成的脉压高度表解决了地形跟踪的难题。

| Abstract: | Application of SAW devices in radar countermeasures is presented in this paper. Channelized receiving of wide band radar signal and 100 percent of probability of intercept can be realized by channelized receiver based on SAW filter banks. With the core of SAW delay line, deception jamming of distance, multiple reply and noise has become one of the comprehensive interference methods against radar signal. On the bases of SAW dispersive delay line, pulsed altimeter has solved the problem of terrain tracing in low altitude penetration. |
