基于在密集的雷达信号环境进行信号分选是一个难题，介绍了一种实用的雷达信号分选技术，给出了基于数字信号处理（DSP）的硬件设计方案，在比较了CDIF及SDIF算法的基础上详细说明了如何实现对信号的有效分选。可分选出的信号有抖动信号、重频参差、频率捷变及频率分集信号等。该设计已经成功运用于某雷达对抗侦察系统，试验效果较好。

Signal classification is a difficult problem in dense radar signal environment. A practical technology for radar signal classification is presented in this paper. After an introduction of hardware layout using DSP, classifying signal effectively is illustrated basing on comparing CDIF with SDIF algorithm. This method is suitable for identifying PRF jittering, PRF staggering,frequency agility and frequency diversity etc. The design is varified as very effective in a radar EWce system.
