摘要
针对传统信号分选算法中单一算法无法分选多种重频调制型信号的缺点,在改进SDIF算法的基础上,对集对分析法进行研究,并将二者结合提出了基于集对分析法的改进顺序差直方图分选算法。仿真实验证明,新方法能够分选多种重频调制类型雷达信号,且在信号量很大的情况下依然具有较高的分选准确率和较好的实时性等优点。
It＇s hard for one traditional sorting algorithm to process multiple PRI type signals. Aiming at solving the problem,an improved SDIF sorting algorithm based on set pair analysis is put forward after a deep study on improved SDIF algorithm and set pair analysis. Simulation results indicate that the new method can sort multiple PRI type signals,and aswell as has high sorting accuracy and high sorting real-time characteristic even when the density of the signal is huge.
