摘要
为正确地对机载预警雷达情报与地面雷达情报关联,提出一种坐标转换模型.该模型分3个步骤将机载预警雷达情报数据从载机坐标系转换到北京54坐标系.相对于通常坐标转换方法,该模型能够有效减小地球曲面误差的影响,使得计算结果具有较高的精度,从而有效地提高情报关联的正确率.
In order to properly correlate the airborne early warning radar intelligence to the ground radar intelligence,a coordinate conversion model was presented,where the model converts the airborne early warning radar intelligence data form the plane coordinate system to Beijing 54 coordinate system in three steps.Relative to the conventional method of coordinate transformation,using this model can effectively reduce the influence of the earth’s surface errors,and make the calculation results with higher precision,thus improving effectively the accuracy of intelligence correlation.
