传统振幅和差单脉冲测角需要伺服控制天线零深对准目标,采集机构角反馈信息,实现对目标的角度测量。采用单脉冲偏轴测角时,应用一种S曲线标定方法,可以直接解算波束宽度内的跟踪到的目标角度信息。介绍了这种算法的标定原理、标定方法、标定应用、标定误差和标定效果,实验数据验证了该方法的有效性。
The traditional amplitude and difference single pulse angle measurement need servo control antenna zero-depth target, collect the angle feedback information, to achieve the target angle measurement. Using single-pulse off-axis angular measurement, the application of a S-curve calibration method can be directly solved within the beam width to track the target angle information. The calibration principle, calibration method, calibration application, calibration error and calibration effect of this algorithm are introduced. The experimental data verify the effectiveness of this method.
