通过对被动微波与红外成像复合导引头在交班时存在对同一目标跟踪点不一致问题的研究,分析出其对同一目标跟踪点不一致的原因.针对此问题,研究了微波相位干涉仪的修正导引规律;推导出实现偏移量修正的导引律,给出工程实施方案.对在交班时因复合导引头跟踪点不一致对弹道产生的扰动影响进行了仿真分析.结果表明:跟踪点不一致问题在交班时对弹道扰动有一定的影响,加入修正导引规律后,弹道参数曲线在末端振荡激烈,需要更大的过载等,说明了偏移量修正的有效性.
通過對被動微波與紅外成像複閤導引頭在交班時存在對同一目標跟蹤點不一緻問題的研究,分析齣其對同一目標跟蹤點不一緻的原因.針對此問題,研究瞭微波相位榦涉儀的脩正導引規律;推導齣實現偏移量脩正的導引律,給齣工程實施方案.對在交班時因複閤導引頭跟蹤點不一緻對彈道產生的擾動影響進行瞭倣真分析.結果錶明:跟蹤點不一緻問題在交班時對彈道擾動有一定的影響,加入脩正導引規律後,彈道參數麯線在末耑振盪激烈,需要更大的過載等,說明瞭偏移量脩正的有效性.

Through the study on the problem that the tracking point is inconsistent when handover for IR/ microwave seeker,the reasons for that were analyzed.Focused on this problem,the adaptive guidance of microwave phase interferometer was researched,the guidance law which modifies the offset was derived and simplified,and the implementation scheme was given.The handover simulation was done considering that the inconsistent tracking point problem.The conclusion is that the tracking point inconsistent problem has influence on trajectory when handover.After using adaptive guidance,the trajectory parametric curve oscillates dramatically at the end and more overload is needed,which shows effectiveness of the adaptive guidance.
