§1引言寻的制导的地-空导弹一般采用比例导航规律,如式(1)所示.为实现式(1)所示的导航规律,须获得视线角变化率. _D=N_1(1) 目前很多地对空、舰对空和空对空导弹都采用雷达型半主动自动跟踪导引头来测量.它一般由接收机、测速陀螺和伺服系统组成.这种系统一般包括两个回路,一个称控制回路,另一个称隔绝回路.隔绝回路的主要作用就是稳定弹上雷达天线,也就是消除弹体对天线的耦合影响.但实际上很难做到完全消除.本文将专门研究消除这种耦合的几种技术措施.
§1 Introduction Seeking guided ground-to-air missiles generally adopt the principle of proportional navigation, as shown in equation (1) .To achieve the navigation law shown in equation (1) At present, many air-to-air, air-to-air and air-to-air missiles are measured by a radar semi-active automatic tracking seeker, which generally consists of a receiver, a tachometer and a servo system. One called the control loop, the other called the isolation circuit.The main role of the isolation circuit is to stabilize the missile on the radar antenna, which is to eliminate the impact of the missile body on the antenna coupling, but in practice it is difficult to completely eliminate.This article will be devoted to eliminating this Several kinds of technical measures of coupling.
