摘　　要：频率步进雷达作为一种高距离分辨率雷达,在精确制导武器中有着广阔的应用前景。主要对毫米波主动导引头频率步进体制的信号处理技术进行研究。分析基于逆傅立叶变换的频率步进信号成像方法,针对该方法的弊端提出了Chirp-Z变换成像方法。介绍其它几种频率步进信号成像方法的特点及应用前景。As a high-range-resolution radar system, stepped frequency radar has great potential applications in accurate missile weapons.This thesis discusses the signal processing of stepped frequency system which is applied in the millimeter wave seeker. Two signal processing methods of high-range-resolution are discussed, that are Inverse Discrete Fourier Transform and Chirp-Z Transform, and then other signal processing methods are summarized and prospected. Talking about the effect of imaging in the different samp...
