摘要
数据链的载波频率、带宽和调制方式是无源探测系统分选识别所需的重要目标特征参数,本文综合仿真了上述通信波形特征参数对循环特征检测器接收机工作特性的影响,将显示循环特征检测器的接收机工作特性对跳频、调制和符号速率的复杂度的结果分成非常敏感、敏感和比较敏感三类,设计复杂的跳频、调制和符号速率等通信波形特征参数以显著降低循环特征检测器的检测概率。
In network centric combat,the passive detection system is the primary threat to the tactical data link,and the carrier frequency,bandwidth and modulation type are the most important target characteristic parameters required for passive detection system to sort and identify the data link.Receiver operation characteristics(ROC)of cyclic feature detector were comparatively simulated for the detection of data link waveform with complex carrier frequency,bandwidth and modulation type characteristics.The results show that the ROC of the cyclic feature detector are very sensitive to the complexity of frequency hopping,modulation and symbol rate.Hence,communication waveform,designed with complex frequency hopping,modulation and symbol rate characteristics,can significantly reduce the detection probability of the cyclic feature detector.
