摘要
为了准确快速地对脉冲多普勒雷达进行识别,选择3个具有代表性的参数:相参性、脉内调制特性及脉冲重复频率进行提取,并讨论了各参数提取的几类理论研究和比较成功的应用方法,分析了脉冲多普勒雷达识别技术中存在的难点及发展方向。
To recognize Pulse-Doppler radar exactly and quickly, coherence, intra-pulse modulation feature and pulse repetition frequency are selected and extracted. Several classes of parameter extraction methods are discussed separately, and the problem and development direction are analyzed.
