A New Method of Sorting Radar Emitter Signals

To sort unknown radar emitter is a significant technique in current information war.A method based on resembling coefficient can sort these signals with different kinds of repeating modulation ways and the pulse repetition intervals is a classical method.Both of them have their own unique advantages,but they also have some disadvantages.A method combining resembling coefficient with PRI is proposed.Firstly,the resembling coefficients between spectrum of radar pulse and rectangular and triangular signal are computed respectively.Secondly,the radar signals are classified by fuzzy C-means according to resembling coefficients,and then the classified signals are sorted with PRI.Simulation results show that this new method is efficient.
