摘要
舰面多天线测距法定位主要是针对着舰引导设备在飞机着舰近距时引导失效或引导精度不高而提出的。利用多副安置在舰船上的测距天线测量与无人机的距离,最终得到无人机相对于舰船位置。着重对该定位方法中的下滑角测量原理和误差进行了理论分析。并通过仿真实验证明了理论分析的正确性以及该方法的良好性能。
Multiple-antennas ranging is a method that uses couples of antennas to measure the distance between UAV and ranging antennas onboard to get the location of UAV. This method is raised to solve the shortage of low precision or locating disability of UAV landing system when UAV is close to the ship. Elevation measurement principle and its error are particularly analyzed. Simulation experiment proves the correctness of theory analysis and good performance of this method.
