Satellite wave beam center estimation method for communication-in-moving system

The invention provides a satellite wave beam center estimation method for a communication-in-moving system. According to the method, appropriate filtering processing is carried out on beacon signals obtained through sampling, an antenna is made to pass through the center position of a satellite wave beam through simple scanning motions, the scanning angles, the angular rates and the signal intensity data of all points are collected in the scanning process, and finally the scanned wave beam center position is calculated accurately by using a first order statistical moment. The satellite wave beam center estimation method for communication-in-moving system solves the problems that a satellite wave beam center scanning and calculating method of the communication-in-moving system of the prior art is easy to be interfered by noise, not high in precision, complex in control process and the like. The satellite wave beam center estimation method for communication-in-moving system can estimate the satellite wave beam center position accurately on satellite signals of different beam widths under noise interference, and has the advantages of being simple in scanning motion control, small in calculated amount, high in precision and the like.
