RTK在机动式脉冲雷达寻北定向中的应用

Application of RTK in Orientation of North Seeking on Maneuverable Monopulse Radar

论文分析全球定位系统实时载波相位差分技术(RTK),提出一种寻北定向方法。通过分别架设基准站和移动站的两个GPS/BD天线,获得以两个GPS/BD天线连线为基线的偏北角,完成雷达快速寻北定向。经过实测数据分析,该方法的测量精度满足机动式脉冲雷达精密标校要求。采用该方法不需要对阵地提前进行方位标设施建设,提高了雷达机动测控和临时任务布站效能,对靶场其它测控装备具有一定参考应用价值。

This paper analyzes the real-time carrier phase difference technology of global positioning system,and proposes a north seeking orientation method. By setting up two GPS/BD antennas of the reference station and the mobile station respectively,the north angle with two GPS/BD antenna lines as the baseline is obtained,and the fast north seeking direction of the radar is completed. Through the analysis of the measured data,the measurement accuracy of the method meets the requirement of the precise calibration of the mobile pulse radar. Using this method,it is not necessary to construct the azimuth vane,and it improves the efficiency of radar maneuver TT&C and temporary task distribution,which has certain application value to other TT&C equipment in the range.
