摘要
传统的窄带雷达,由于其距离分辨能力远大于通常目标的尺寸,因而,雷达对目标特性(包括其动态特性和散射特性)的测量只能是整体的、宏观的。宽带雷达,当其距离分辨率小于或远小于通常目标尺寸时,雷达则可测量目标的微观特性(包括微动态特性和微散射特性)。从技术发展的角度分析了窄带雷达测量、宽带雷达测量、距离多普勒测量、相位距离测量等目标特性测量技术。
In classical narrowband radar, the target characteristics （dynamic and scattering） are measured macroly and wholly, as the range resolution capability of it is much larger then the dimension of common radar target. But in the width band radar, the target characteristics can be measured mivrolly because of it＇s range resolution capability much less then the dimension of common target. Based on the history of technical development, Narrow-band radar target characteristics measuring technique, width band radar target characteristics measuring technique, range-doppler measuring technique, phassed-range measuring technique are analysed in the paper.
