摘　　要：BOC调制方式由于抗干扰能力强、测距精度高,在导航系统中得到了广泛应用。但是BOC调制方式的自相关函数多峰特性与频谱分裂特性为非协作方导航信号的侦测带来了巨大困难,本文首先从BOC调制原理和信号特点出发,分析了对非协作BOC信号检测估计和捕获跟踪的要求,介绍了非协作BOC信号检测估计技术现状;然后分析了传统信号检测估计算法对BOC信号的适用性,比较了现有非协作BOC信号检测方法的优缺点,并给出了发展建议;并且针对BOC信号捕获跟踪时的模糊问题,介绍了现有无模糊捕获和无模糊跟踪技术的发展情况,最后展望了无模糊捕获跟踪的发展方向。BOC modulation is widely used in navigation system because of its strong anti-jamming ability and high ranging accuracy.In order to detect non-cooperative navigation signals,this paper discussed the detection and acquisition and tracking technology of non-cooperative BOC signals from the perspective of navigation confrontation.Based on the principle of BOC modulation and signal characteristics,the requirements for detection,estimation and acquisition and tracking of non-cooperative BOC signals were analyzed.The status quo of non-cooperative BOC signal detection and estimation technology was systematically introduced,and the applicability of traditional signal detection and estimation algorithms to BOC signals was analyzed.The advantages and disadvantages of existing non-cooperative BOC signal detection methods were simulated and compared,and development suggestions were given for BOC signals.The problem of ambiguity in acquisition and tracking was discussed.The development of the existing technologies of no-ambiguity acquisition and no-ambiguity tracking was given.Finally,the development direction of no-ambiguity acquisition and tracking was prospected.
