multiple-input multiple-output radars hybrid genetic algorithm transmit beamforming
A method of realizing transmit beamforming by designing the cross-correlation matrix of transmit signals to establish a desired beam pattern is studied,which uses modern optimization theory.A mathematical model of designing a beam pattern is set up,and the method can get the optimized result by minimizing the cost function.The desired spatial transmit beam pattern can be approximated by using the hybrid genetic algorithms to optimize the cross-correlation matrix of transmit signals of multiple-input multiple-output(MIMO) radars.The simulation results testify the validity of the method.
