摘　　要：传统的信号分选算法建立在脉冲描述字(PDW)参数分析的基础上,对同频或频谱混叠的雷达信号可能无法分选。鉴于越发明显的常规雷达信号处理方法的局限性,通过仿真手段,用盲源分离的方法对混合后的雷达信号进行分选。仿真结果表明,该方法可对雷达盲信号进行有效的分离,且不需要其它信号处理方法所要求的任何先验知识作为条件。Traditional signal sorting algorithms are based on pulse decription word （PDW） parame- ter analysis,and the radar signals with common frequency or superposition spectrum may not be sorted. For the limit of conventional radar signal processing methods become more and more obvi- ously, this paper uses blind source separation method to perform sorting to the mixed radar signals through simulation means. The simulation result shows that the method can separate the blind sig- nals of radar effectively,and need not take any prior knowledge as the condition, which is required by other signal processing methods.
