摘要
为应对超低空突防带来的严重威胁,仿真分析了双基地雷达距离探测精度随双基地角的变化关系,综合考虑了双基地角临近180°的无效探测区域,以及不同单双基地角下的雷达截面积等因素,对单基地雷达、地基双基地雷达和空地双基地雷达在超低空区域对巡航导弹等目标的探测能力进行对比分析。仿真结果表明,目标在大双基地角下雷达截面积会显著升高,空地双基地雷达在超低空区域具有显著的探测优势,可以为现役单基地雷达的超低空补盲雷达设计提供参考。
In response to the serious threat brought by very low-altitude penetration,a simulation analysis about the relationship between range detection accuracy and bistatic angles is made.Considering the radar cross section in different monostatic and bistatic angles and the detection blind zone caused by near180°bistatic angles,a comparative analysis about detection range of very low-altitude regions of monostatic,ground b istatic and air-ground bistatic radars is made.The results show that the target has bigger radar cross section in great bistatic angles and air-ground bistatic radar has obvious detection advantages in very low-altitude r egions.It can be used as a reference for designing the very low-attitude gap-filling radar.
