Abstract :
Sorting rate of current methods is not high and too sensitive to the signal noise ratio (SNR), in order to solve this problem, a novel characteristic for sorting radar emitter signal is proposed. The ambiguity function of received signal is extracted and predigested to two-dimension 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 ambiguity function of different signal is distinguishing and not sensitive to SNR, the resemblance coefficients are divisible and steady. The advantage of this new method is validated by simulation result, and the lowest sorting rate is 90% at SNR = 10 dB.
