一种机载雷达机械扫描空域稳定改进算法

机载雷达在载机机动时，为保证天线视线空域指向范围不变，采用空域稳定的算法。当给定的方位和俯仰指令不在同一坐标系时，采用传统的算法会使得实际的空域与理想空域在载机机动幅度较大时有很大误差。文章提出一种算法，使得雷达扫描中心精度与期望值十分接近。同时，对于坐标转换中方位和俯仰的指令间覃相影响引起的俯仰指向精度降低问题，提出...

An Improved Algorithm for Airborne RadarMechanical Scarring Airspace Stabilization

Airspace stabilization algorithm is designed for aircrafts to keep their antenna beams pointing to a fixed area when there are maneuvering. When given azimuth （AZ） and elevation （EL） instruction are not in the same coordinates, worse performance will get as bigger maneuvering occurs when using traditional algorithm. In this paper, an algorithm was given which could make radar scan center accuracy very close to expected value. As EL instruction getting worse during coordinate-transformation due to interaction of AZ and EL instruction, a solution was given. By the combination of these two methods, airspace stabilization performance would be improved.
