Abstract
A method and a device for constructing a redundancy-removed coprime radar array based on one-bit quantization. The method includes obtaining a first sub-array element and a second sub-array element both used for constructing a redundancy-removed coprime radar array, and determining a redundancy-removed coprime array respectively corresponding to the first sub-array element and the second sub-array element by a graph theory method; obtaining target echo data of the redundancy-removed coprime array, and obtaining a target radar array by performing one-bit quantization on the target echo data for completing array cavities of the redundancy-removed coprime array; moreover, before the completing, positions of all non-empty array elements in a redundancy coprime array are used to place radars, and before the completing, the radars are not arranged in positions of empty array elements.
