Time modulation array sideband suppression beam control method for radar communication integration

The invention discloses a time modulation array sideband suppression beam control method for radar communication integration, and belongs to the technical field of radar communication. According to the invention, the problem of low energy efficiency of the time modulation array caused by sideband radiation in a radar communication integrated scene is solved. According to the method, the uniform linear array is used for receiving and transmitting signals, then the positive and negative alternating periodic function is used for periodically modulating the uniform linear array, and finally parameters are optimized, so that the parts of the time modulation array except for + 1-order harmonic components and-1-order harmonic components are as small as possible by optimizing the parameters, that is, the energy loss is as small as possible; and the +1-order harmonic component after the radiation field intensity parameter optimization of the time modulation array is used for communication, and the-1-order harmonic com
