摘　　要：通过对平台罗经和雷达稳定转台的结构分析,说明大地极坐标系与雷达稳定转台极坐标系之间的二阶电子稳定方程与实际设备空间运动情况比较符合。通过剩余误差法和二阶电子稳定方程的对比分析,在三轴稳定转台雷达的补偿修正中,当纵、横摇剩余误差的瞬时值<1°时,采用舰载雷达天线电子稳定方程的剩余误差法可以直接作为二阶电子稳定方程的替代方案应用。By analyzing the structure of the platform gyrocompass and the radar stabilizing rotaryplatform, it is shown that the two？order electronic stabilization equation between geodetic polar coor？dinate system and radar polar coordinate system of the stabilizing rotary platform is in good agreementwith the actual space motion of the equipment. With the comparison and analysis of the residual errormethod and the two？order electronic stabilization equation, in the compensation and correction of theradars with the three？axis stabilizing rotary platform, when the instantaneous pitch and roll residualerror values are less than 1°, the residual error method of using the electronic stabilization equationfor the shipborne radar antenna can be directly used as an alternative solution of the two？order elec？tronic stabilization equation .
