基于相参雷达信号自相关函数的分选方法

Sorting Method Based on Coherent Radar Signal Auto-correlation Function

为解决信号分选中的"漏批"问题,提出了一种基于相参雷达信号自相关函数的分选新方法。该方法利用相参信号的瞬时自相关函数,建立了峰值比判决模型,并对该模型进行分选仿真应用。仿真结果表明,在信噪比高于5 d B时,方法能够解决单频、线性调频、非线性调频脉冲串信号一次分选过程中的"漏批"问题,验证了所提出方法的有效性。

To solve the Increasing-batch problem in signal sorting, a new sorting method based on auto- correlation function of coherent radar signal is proposed in this paper. By using the instantaneous autocorrelation function of coherent signal, the discrimination model of ratio of peak values was built and applied in sorting simulation. Simulation results show that the proposed approach can solve the Increasingbatch problem for CW,LFM,NLFM one sorting when the signal-to-noise rate （SNR） above 5dB. The validity of the approach is demonstrated by experimental results.
