【摘要】 本文针对某车载火炮武器系统在某次检飞试验的雷达跟踪精度评定中出现的“跟踪雷达俯仰测角精度超差”问题进行了深入的原因分析，将问题原因定位为：在系统方位运转工况下，雷达俯仰零位与绝对水平度间误差超差。该误差属于制造误差范畴，在系统方位运转时对雷达俯仰测角精度的影响无法消除。因此提出了精度评定时在雷达俯仰角度值中引入一种修正方法，以尽可能减小该误差对俯仰角精度的影响，并通过原有检飞数据仿真验证了这种补偿方法的可行性。更多还原

【Abstract】 This paper analyzes the reason for very poor elevation measurement accuracy of the tracking radar of a vehicular artillery weapon system in a test. The cause of the problem is determined to be the large difference between elevation zero position of the radar and absolute level(i.e., levelness error) when the system is moving in azimuth. This error belongs to the category of manufacturing error, and the impact of the error on radar elevation measurement accuracy cannot be eliminated when the system is moving in azimuth. Therefore, a compensation method is employed in radar elevation measurement to minimize the impact of the error on the elevation measurement accuracy. In addition, a simulation using original test data is performed. The simulation results prove the feasibility of the compensation method.更多还原
