摘要
针对单屏篱笆加波束跟踪探测方式,提出目标过屏的算法和雷达波束跟踪算法,分析单站部署地理位置、屏幕张角和跟踪雷达截止高度角对探测目标覆盖率的影响,研究不同多站组合方案的覆盖特性。实验计算结果表明:1)若跟踪波束截止高度角不变,随屏幕张角的增大,覆盖率存在极大值,且测站纬度越高,极大值出现越早;2)随截止高度角增大,目标覆盖率先缓慢减小,而后迅速下降,测站经度对覆盖率影响较小,纬度优先与大三角组合方案的目标覆盖率差别较小,且优于经度优先的组合方案。
Aimed at the detection mode of single fence and tracking-beam the algorithm of target passing through screen and radar tracking-beam algorithm are proposed in the paper.The influence of geographical location of single station deployment,screen angle and radar cut-off angle on detection target coverage rate is analyzed,and the coverage characteristics of different multi-stations-combination schemes are studied.The results show that if the cut-off angle of the tracking beam is constant,the coverage rate has an extreme value with the increase of screen angle,and the higher the station latitude,the earlier the extreme value appears.With the increase of the cut-off angle,the target coverage decreases slowly at first and then rapidly.The longitude has little influence on the coverage of the station.The difference of target coverage rate between latitude first and large triangle combination scheme is small,and it is better than that of longitude priority.
