| 摘 要： | 考虑目标姿态角对目标跟踪/识别中的雷达RCS值的影响,建立了雷达测量坐标系与目标体坐标系之间的坐标转换模型.将雷达转换为姿态角不断变化的目标体坐标系下一点,研究雷达视线在目标体坐标系下的方位和高低角.利用Matlab对其进行仿真,得出雷达视线方位和高低角随时间变化的曲线,有效验证了坐标转换模型的正确性和重要性.

| Abstract: | Considering variational Radar RCS which changes along with variational carriage of target in the tracking and recognising target,this paper brings forward a method which makes a model of coordinate transform between Radar and target coordinate.Considering Radar as a point in variational target body coordinate,we can study the azimuth and elevation of line of sight of radar in target body coordinate.Using Matlab to simulate the coordinate transform,we gain the curves of the azimuth and elevation.Through this... |
