基于PRI变换和小波变换的雷达信号分选

Sorting of Radar Signal Based on PRI transfer and wavelet transfer

分析了脉冲重复间隔(PRI)变换算法和小波变换算法的基本原理,针对两种算法在雷达信号分选中的优缺点,提出了一种基于PRI变换和小波变换相结合的雷达信号综合分选方法。该方法首先利用PRI变换对雷达信号粗分选,然后应用小波变换进行细分选。仿真结果表明,在信噪比不低于10dB的条件下,该方法准确可行。

The PRI transfer algorithm and wavelet transfer algorithm is analysed firstly, then a method of radar signal sorting is proposed in this paper based on the advantages of the two algorithms. Firstly, the PRI transfer is applied to sort radar signal coarsely, then the wavelet transfer implements signal subdivision. The simulation results show that the method is exactly when SNR is not less than 10dB.
