To solve the problem of beam direction alteration caused by platform disturbance in phased array systems, a strapdown beam stabilization method is proposed. The method is utilized within a single module composed of an angle rate sensor and a signal processor, and dispenses with accurate initial attitude. The angle rate sensor measures the rotation rate of the antenna caused by the platform disturbance. The signal processor finds the compensation angle iteratively and controls the beam direction. Algorithm simulation and experiment with a monaxial rotary motor to simulate the platform disturbance show that with the implementation of the strapdown beam stabilization method, the angle errors decrease visibly and the isolation rate of the system improves significantly. Hence the method is effective in reducing the impact of platform disturbance on beam direction. It is easy to use and can be applied to miniaturized platforms such as those on unmanned planes.
