摘要
针对三坐标雷达双波束测高精度低及高度突跳问题,提出四波束测高方法,该方法在满足信号处理能力的情况下,采用四波束测量,利用回波幅度较大的两个波束进行仰角测量。用雷达设备进行实际测飞实验,测飞结果表明,该方法可以有效地提高测高精度,改善高度突跳现象。
Aiming at the problems of height jumping and low height-measurement accuracy of 3D radar in height measure-ment method of dual beam,a height measurement method of four beam is proposed,which uses two beam with larger amplitude echo signals for elevation angle measurement and the method satisfies the ability of signal processing. The actual flight experi-ment is carried with the radar equipment,and the experiment results show that the method can effectively improve the height measurement accuracy and solve the problem of height jumping.
