基于同步脉冲的模式5信号个体识别方法
Specific Emitter Identification for Mode 5 Signal Based on Synchronous Pulse
摘要
Abstract
Mode 5 signal used in the identification friend or foe(IFF)system adopts technologies such as Walsh soft spread spectrum and MSK modulation to improve the information capacity and security,while making specific emit-ter identification(SEI)of the Mode 5 signal difficult.To address this issue,two SEI methods for Mode 5 signal are pro-posed by using the fixed characteristics of synchronous pulse:SEI method based on the instantaneous phase features of synchronous pulses and SEI method based on the cross-correlation features of synchronous pulses.The simulation results show that under the condition of signal-to-noise ratio of 12 dB,the accuracy of the method based on the instanta-neous phase feature is 90.4%,and the accuracy of the method based on the cross-correlation feature is 94.8%.The per-formance of both SEI methods proposed in this paper is better than the traditional ones.关键词
