| 摘 要： | 提出了一种动态条件下通过船载经纬仪和雷达标校电视联合测恒星,标定雷达轴系误差修正参数的数学方法,从理论上推导了相关的模型。在此基础上,通过实测数据进行了试算分析。分析结果表明:利用动态标定方法给出的船载无线电雷达轴系误差修正参数吸收了经纬仪光轴和雷达光轴之间的偏差,有效提高了雷达测角精度。

| Abstract: | A new parameter-correction technique is proposed, which can calibrate the radiometer shaft parameters by means of radar-theodolite joint star observation.The related model is derived and linked with practice.By using this technique,the related task data is analyzed. The results indicate that the ship-borne radio shaft parameters corrected by the dynamic calibration can eliminate the error between the radio optical axis and theodolite optical axis. The technique can obviously improve the measurement accuracy of the ship-borne radio system. |
