The Study of Marine Intelligent Antenna Technology Based on Beamforming Algorithm

Abstract

Maritime communication system is an important part of real-time battlefield information transmission. In this paper, adaptive smart antenna beamforming technology is applied to maritime communication, and a one-dimensional antenna array structure model and signal model are proposed. At the same time, the adaptive beamforming algorithm in smart antenna is studied. Since the classical LMS beamforming algorithm has slow convergence speed and poor adaptability, genetic algorithm is applied to array antenna beamforming in this paper. And the traditional genetic algorithm is optimized and improved in initial population planning and crossover operation. The simulation results show that compared with LMS algorithm, traditional genetic algorithm and the optimized genetic algorithm has better convergence effect of mean square error, more accurate suppression of interference signal by beamforming, better practicability and development potential.
