| 摘 要： | 对于舰载三坐标相控阵雷达,要保证其在大地坐标系内的空域覆盖及对目标的稳定跟踪,就需要通过动平台补偿来修正波束指向,而波束修正时采用的舰姿态信息会将它的误差引入到雷达的测量误差中,从而影响到雷达的测量精度。只有将这一误差关联效应的机理分析清楚,才能在雷达输出数据出现跳变时有效的隔离出误差来源,正确评估雷达性能。

| Abstract: | For the ship-borne 3D phased array radar,in order to realize airspace coverage in geodesic coordinates and stable tracking of targets,moving platform compensation is required to achieve correction for beam direction.During beam correction,the error from ship attitude information will be also included in radar measurement errors so as to affect accuracy of radar measurement.Only if the mechanism of error correlation is analyzed thoroughly,then is it possible to effectively isolate error sources and correctly evaluate radar performance while output data of radar occurs sudden change. |
