摘要
针对低截获概率(LPI)通信信号侦测需求,通过分析扩谱调制信号的低截获特性和对其侦察存在的问题,提出了一种基于孪生通道自相参的LPI通信信号接收方法,并将其与非相参处理和常规相参处理方法进行了对比,可知该方法在相同的信号积累次数和信号处理时间下具有接收灵敏度更高、适用信号范围更广、应用场景更广泛等特点,具有较好的应用前景。
Aiming at the requirement of low probability of intercept(LPI) communication signal detection,by analyzing the low interception characteristics of spread spectrum modulation signal and the problems existing in its reconnaissance,a LPI communication signal receiving method based on twin channel self-coherent is proposed,and non-coherent processing and conventional coherent processing methods are compared with it. It is concluded that the method has higher receiving sensitivity,wider applicable signal range and wider application scenarios under the same signal accumulation times and signal processing time,and has good application prospects.
