摘要
针对现有雷达标定系统存在的使用成本高、组织实施不方便、真值获取手段不可靠等一系列问题,提出了利用搭载"北斗"卫星定位系统的旋翼无人机作为探测目标的三坐标雷达精度标定新方法。设计了基于该方法的三坐标雷达标定系统方案,研究了系统实现所需的关键技术,最后给出了系统样机的试验结果。结果表明,该方法能够真实反映三坐标雷达的系统误差,与传统雷达标定方法相比,更加经济、简便、灵活。
For the problems of existing radar calibration systems,such as high cost for application,incon-venient organization and implementation,unreliable obtaining way of true value,a new method for calibra-ting three-dimensional radar accuracy is proposed by taking the unmanned gyroplane carrying Beidou satel-lite location system as the target of detection. The calibration scheme for three-dimensional radar is de-signed according to the proposed method. The key technologies for the system implementation are studied.Finally,the test results of the system prototype are given. The results show that this method can truthfullyreflect the system error of three-dimensional radar and compared with the traditional radar calibrationmeasurements,it is more economic,much simpler,and more flexible.
