摘　　要：提出了舰载一维相控阵雷达波束电子稳定的计算方法,弥补雷达波束随舰船摇摆而导致的指向偏移,取代机械稳定平台修正偏移量,满足空域覆盖。文中分析了基本的坐标变换,采用矢量旋转变换的方式研究了一维相控阵雷达的波束稳定,给出了波束稳定的计算公式,通过仿真验证了计算方法的有效性。该方法为工程实现提供理论支撑。A calculating method of shipberne 1 D phased-array radar beam electronic stabilization is put fonvard, so as to compensate the pointing deviation caused by radar beam moving with ship rocking, which can replace mechanical stabilization system modification and satisfy space coverage. Firstly, basic coordinate transform is analysed and electronic beam stabilization of 1D phasedarray radar is studied by revolving vector transform method. Then, a calculated formula of beam stabilization is presented. The effectiveness of this method is validated by simulation and it is able to provide theoretical support for engineering.
