本发明是有关在初、中段采用半主动寻的制导,末段采用主动寻的制导的复合制导导弹。一般说来,在采用半主动制导和主动制导时,导弹所接受目标产生的多普勒频率,视照射目标的发射频率不同,以及照射源和目标所构成的角度不同而异。因而,以往的复合制导导弹从半主动制导转换为主动制导后,往往不知道目标的多普勒频率,因而必须从新探测目标。因此,采用旧的复合制导时,往往在最为关键的末端——从半主动制导转换为主动制导时,失去目标。所以制导精度很差。
The present invention relates to a semi-active seeking guidance in the early and middle stages and a composite guided-missile in the last stage using actively seeking guidance. In general, the Doppler frequency of a target received by a missile during semi-active guidance and active guidance varies depending on the firing frequency of the target and the angle of the source and target. Therefore, the conventional composite guided missile conversion from semi-active guidance to active guidance, often do not know the target Doppler frequency, which must be re-detection of the target. As a result, with old composite guidance, goals are often lost at the most critical end - from semi-active guidance to active guidance. So the guidance accuracy is poor.
