主要概述一种实验弹载多卜勒雷达倒置接收机的基本原理,给出了其实验框图.倒置接收机具有优良的抗杂波性能,是弹载单谱线速度跟踪系统的一种优选体制.对倒置接收机的主要部件——固体微波源、锁相移频环、混频前中组件、窄带晶体滤波器、窄带晶体鉴频器、环路压控振荡器、高增益大动态中频道道和搜索截获电路都作了论细介绍.实验结果表明,该倒置接收机完全满足设计要求.

The basic principle of a kind of experimental Doppler radar inverted receiver is briefly introduced, and its experimental block diagram is given. The inverted receiver has excellent anti-clutter performance and is a preferred system for the missile single-track velocity tracking system The main components of the inverted receiver - solid microwave source, phase - locked loop frequency shift, mixing before the middle components, narrowband crystal filters, narrow band crystal frequency discriminator, loop voltage controlled oscillator, high gain large dynamic channel Road and search intercepted circuit are discussed in detail.Experimental results show that the inverted receiver fully meets the design requirements.
