摘　　要：先进的脉冲多普勒 (PD)雷达采用的信号脉冲具有相参性 ,又能进行相关处理 ,极大地提高了其抗干扰性能。而声表面波延迟线输入输出载频不变 ,并能始终保持脉冲的相参性 ,用于 PD雷达欺骗干扰 ,是实用的方案。文章介绍了研制的声表面波可编程延迟线和多抽头延迟线组件 ,首次用于 PD雷达欺骗干扰 ,应用前景良好。Pulse signals in advanced Pulse Doppler(PD)radar have features of coherence and correlation,thus can greatly improve the anti interference ability of the radar.The input and output carrier of SAW delay line is constant to maintain the coherence of the pulse,which can be well applied for deception jamming in PD radar.This paper firstly presents such programmable delay line and multi tapped delay line banks used in PD radar,which is believed to have large application potential.
