Sorting algorithm for pulse radar based on wavelet transform

Pulse sorting is a key part of electronic reconnaissance which is widely used in the modern warfare. In order to suppress the sub-harmonic phenomenon that occurs in the statistical histogram sorting algorithm and solve the problem of poor clustering effect of the current clustering sorting algorithm, a sorting algorithm for radar signals based on haar wavelet transform is proposed. The simulation results show that the new algorithm has a high accuracy of measurement time and good intra-class aggregation, inter-class separation, with a high sorting accuracy at low signal to noise ratio. Haar wavelet transform can be used as a powerful tool for sorting of radar signal.
