【摘要】 雷达技术 60年来取得了巨大的发展 ,特别是随着现代计算机技术和现代信号处理技术的成熟与发展 ,使雷达由参数测量向非参数测量发展 .雷达对目标的识别成为新一代雷达的发展重点 .文中应用小波变换技术 ,对多普勒体制雷达的音频信号进行分析 .从其中一个距离波门获取的多普勒信号中成功地提取了目标的数量等信息 .也就是取得了对目标的高分辨率 .且计算速度快、数据量小 .有利于实现实时信号处理更多还原

【Abstract】 The technique of readar has very rapid developed.Especially,with the development of computer and signal processing,radar has developed from parameter measurement to non parameter measurement.Object recognition has become an emphasis of new generation of radar.By means of wavelet transform,it has analyzed the doppler signal obtained from one distance gate of a active duty radar,and has successfully distilled the quantity message of the objects,that is a high resolution of a object has gathered.This is a rapid method using less data than the others.It improves the traditional technigne and is favourable for datum real time process.更多还原
