船载外定标雷达波束照射区域定位方法研究

摘要

针对岸基海杂波测量雷达下视外定标过程中,由于受到涌、浪、风等外部环境的影响,导致船载外定标设备偏离定标位置,影响外定标测量实验数据的有效性问题,该文提出了一种船载外定标雷达波束照射区域的定位方法,结合GPS技术,实时显示船载外定标设备在岸基雷达波束照射区域中的位置以及相对于雷达波束的方位,当偏离设定的定标位置或方位范围时,给出报警提示,有助于实时的调整船载外定标设备的姿态.该文研究方法在某岸基L波段雷达海杂波外定标实验中得到应用,不但确保了实验数据的有效性,同时提高了实验的效率.%In the outside calibration of process based on shipborne sea clutter measurement radar,the outside calibration equipment will deviate from calibration position because of the influence of wind, wave and surge,the experimental data of outside calibration are directly affected.This papar proposes a position method for shipborne outside calibration based on radar beam irradiation area.It can show the position of shipborne outside calibration equipment in the radar beam irradiation area and relative azimuth of radar beam based on the technology of GPS. When the calibration equipment deviate from a set position or orientation,the alarm is helpful to adjust the attitude of shipborne outside calibration equipment. in this paper,the research methods are applied in the land-based sea clutter L-band radar outside calibration experiment,not only ensures the validity of the experimental data,and improves the efficiency of the experiment.
