A New Method for Sorting Radar Signals Based on Coherency

Radar can work on different wave bands in different period of time, which result in the Increasing-batch problem based on the existing methods of signal sorting. In order to solve this problem, Slope Discriminance was proposed in this paper. Error analysis of this proposed method shows its availability when the measurement error of frequency of receiver is below 100MHz. Simulations on same and different radiant points was given. The results show that this new method decreases the possibility of Increasing-batch and also it can be a supplement of present methods.
