High-power microwave phased-array antenna beat wave radiation method and system

The invention relates to a beat wave radiation method and a radiation system, and provides a high-power microwave phased-array antenna beat wave radiation method and a high-power microwave phased-array antenna beat wave radiation system in order to solve the technical problems that when a beat wave HPM is radiated through an antenna, two phased arrays are adopted to radiate microwaves of two frequencies respectively, the number of phase shifters is large, the cost is high, and the structure is complex. According to the invention, phase shifting is carried out on microwaves corresponding to each sub-array, then phase shifting is carried out on radiation microwaves corresponding to each antenna array element, a sub-array + array element two-stage phase shifting method is adopted, and compared with an existing scheme that g * M * N phase shifters are needed for realizing beat wave radiation, only M * N + g * U * V phase shifters are needed, so that the number of the phase shifters is greatly reduced, and the cos
