Abstract :
In this paper, a novel sorting algorithm for radar emitter signal is proposed. The bispectrum of received signal is extracted, and it is predigested to two dimensions characteristic. A rectangle pulse sequence and triangle pulse sequence are constructed, then the resemblance coefficient of two dimensions characteristic with rectangle pulse sequence and triangle pulse sequence are gained, and they are used as the sorting parameters. For the bispectrum of different signal is distinguishing and it is not sensitive to SNR, the resemblance coefficient is divisible and steady, the advantage of this new method is validated by simulation results, and the highest sorting rate is 100% when the SNR is 10 dB.
