摘要
首先阐述了捷联干涉仪体制被动导引头测角模糊现象出现的机理,并分别针对导引头处于目标截获和目标跟踪2种状态下鉴相模糊现象作了分析。在此基础上,提出了目标截获和目标跟踪2种状态下导引头测角解模糊算法,算法基于地面站实时给导弹粗装订的弹目相对方位角数据。最后,给出了目标截获时角度容限及目标跟踪时相位容限的确定方法。
The theory of the angle-measure ambiguity about the passive seeker which adopts the strapdown phase-interferometer system is introduced firstly,and the phenomena of the angle-measure ambiguity when the seeker is in object-capture or object-trace state are analyzed.Then the method to resolve the angle-measure ambiguity is put forword,and the method about how to decide the angle-threshold and the phase-threshold is presented.
