| 摘 要： | 导弹雷达引信依靠波束换接控向和回波信号比幅技术，可以获得近场目标脱靶方位信息，既可以为定向战斗部提供起爆方向，又可以为引信起爆控制提供关键参数。该文分析了雷达引信探测和识别脱靶方位的目的，描述了脱靶方位信息的特征，给出了实测的飞机目标近场多普勒信号，提出了两种具有实用性的多普勒信号比幅算法，并给出了验证结果。

| Abstract: | Missile radar fuze can obtain near field target miss distance direction by switching beams and comparing echo Doppler amplitude.The direction information can offer the explosive azimuth for directional warhead and is key parameter of fuse ignition.The purpose of radar fuze detecting and identifying the miss distance direction was analyzed.The information characteristics of miss distance azimuth were described.Some testing Doppler signals from 4 detection beams are given.Two practicable algorithms of Doppler amplitude comparison are presented,and the experimental result is given. |
