In this paper, the traditional LMS algorithm is extended to the real-time multi-reference point algorithm. The adaptive tracking beam is obtained by the mean square error and the minimum optimization criterion. Finally, this paper presents a switching proposal of the tracking beam. In order to better realize the effect of the proposal, the sum of minimum mean square error criterion is discussed, and the central optimal principle is proposed to choose feed combination. The central optimal principle proposed in this paper can select a more suitable combination of feeds to form the tracking beam, and then obtain a better adaptive tracking effect.
