摘　　要：航空航天测控系统中,相干测距和非相干测距均存在距离模糊问题,限制了其有效测距范围。针对这一问题提出了在双通道抗模糊测距方案,利用2个通道的测距差值解测距模糊,对测距范围、测距精度和测距周期等指标之间的耦合关系进行了分析。分析结果表明,双通道测距方法有效地解决了测距模糊问题,在很大程度上扩大了测控系统的测距范围。In aerospace TT＆C system,both coherent and incoherent ranging methods undergo the range ambiguity problem,which limits their effective ranging scope.To solve this ambiguity problem,a dual-channel anti-ambiguity method is proposed.In this method, the difference value between two channels is used to solve the ranging ambiguity. Further on,the coupling relationships within ranging seope,ranging resolution and ranging period are analyzed in detail.Analysis results show that the ambiguity problem could be solved by dual-channel ranging method, and at the same time, the ranging scope would be expanded in a great level.
