Wide-angle scanning mixing array supersparsity layout method without grating lobes

A wide-angle scanning mixing array supersparsity layout method without grating lobes relates to an antenna. A mixing array supersparsity layout method of a secondary inhomogeneous interval subarray is employed, namely a simulation multi-beam forming network is employed in the subarray, and different phase shift magnitudes are configured for the array elements to allow the subarray wave beam to realize the wide-angle airspace scanning. A plurality of subarrays are subjected to layout at inhomogeneous intervals to form a total array, after each subarray is outputted, the analog-digital sampling is performed, and one single subarray only need one digital channel so as to greatly reduce the number of the channels. The genetic algorithm is employed to optimize the distances of the internal subarray and between the subarrays, the minimum distance is controllable, and the side lobes and the grating lobe level can be inhibited in the condition of the wide-angle scanning to obtain a mixing array sparse layout with the
