摘要
红外搜索系统安放在车载桅杆上升高使用,可以提高系统的探测距离。但由于车载桅杆的误差引入,系统的测角精度误差会增大。本文对桅杆型红外搜索系统的测角精度误差来源进行了分类和估算,提出了一种利用双天线差分GPS和姿态测量设备进行全系统测角精度评估的新方法。工程实践表明,该方法不仅可以快速完成测角精度标定,而且标定结果和理论计算结果基本一致。
In order to increase the detection range of the system, IR searching system is equipped on top of a vehicle - mounted mast. As the mast is introduced, angle measurement of the system is strongly influenced. On the basis of error classification and error analysis of angle measurement, a new method based on double antenna differential GPS and attitude measurement is proposed to accomplish the evaluation of angle measurement precision for the whole system rapidly. The results show that this method can rapidly achieve the calibration of angle measurement precision, and the measuring results are in good agreement with theoretical calculation.
