摘要
针对大地坐标系下雷达波束覆盖范围随着舰船摇摆不断变化这一现象,提出一种在正弦空间下计算该覆盖范围的方法。利用正弦空间中波束形状不变的特性,将大地坐标系映射到正弦空间中;然后进行等间隔取点计算;最后通过仿真验证了该方法的可行性,可为舰船摇摆下的波束调度提供理论依据。
In view of the fact that the coverage of radar beams is constantly changing with the ship swing in the geodetic coordinate system,a method of calculating the coverage based on the sine space is proposed.The characteristics of the beams with invariable shapes in the sine space are utilized,and the geodetic coordinate system is mapped to the sine space for calculation of evenly spaced points.The method proves to be feasible via the simulation,providing a theoretical basis for beam scheduling under the ship swing.
