对地毫米波脉冲多普勒雷达导引头分阶段变参数设计

The Two-Stage Parameters Design Method for MMW Pulse Doppler Radar Seeker

根据对地毫米波脉冲多普勒雷达导引头搜索段与跟踪段的不同特点,提出了分阶段变参数的导引头参数设计方法。对导引头在搜索段目标多普勒频移与地杂波谱进行了深入分析,并分别给出了导引头在两不同阶段下的参数设计准则。最后通过实例分析与仿真对该参数设计方法的实用性进行了验证。

According to the different characters of searching and tracking stage of air-to-surface MMW pulse doppler ra- dar seeker,the two-stage parameters design method for the seeker is presented.The analysis on the target doppler frequency and clutter frequency spectrum when the seeker is under the searching stage is deeply analyzed,and the pa- rameters design rules for the searching and tracking stage is put forward.Then the instance of parameter design is given to validate the practicability of this method.
