摘　　要：介绍了一种主动防护雷达的角度标校方法。该主动防护雷达采用相位和差单脉冲测角方式,由于雷达体积小、作用距离近,可以利用光电经纬仪搭建简易的角度标校测试场,通过标校望远镜和信号源标定角度。分析了这种方法带来的标定误差,指出被测雷达与信号源之间的距离越远标定误差越小。角度标定后,可以通过修改角误差曲线校准角度。最后给出了主动防护雷达利用这种标校方法后的测角误差,实测数据表明这种标校方法可以提高主动防护雷达的测角精度。This paper introduces a kind of angle calibration method for active protection radar.The phase and difference single pulse angle measurement is used in the radar.Because of the small size and the distance of the radar,this methoduses photoelectric theodolite,calibration telescope and signal source to set up a simple angle calibration test field.The calibration error of the method is analyzed,and the further distance between the measured radar and the signal source is,the smaller the error is.It can be calibrated by modifying the angle error curve after angle calibration.The measurement error of the active protection radar using the calibration method is presented.The measured data show that the angle calibration method can improve the measurement accuracy of the active protection radar.
