The invention discloses a sparse array arraying method based on cascading of three uniform linear arrays and application, three uniform linear arrays are used for arraying, mutual coupling influence is reduced by setting array element spacing of a large sub-array, meanwhile, reasonable sub-array spacing is set, a large-aperture virtual uniform linear antenna array can be obtained, and then non-fuzzy high-precision DOA estimation can be completed. According to the method, array element positions of three subarrays in existing three-uniform linear array cascading are improved, a low-mutual-coupling array based on three-uniform linear array cascading is constructed, the optimization target that the weight value of an element smaller than the subarray element distance in a difference set is 1 is achieved, the mutual-coupling leakage phenomenon existing between existing sparse array type array elements is effectively improved, and the method is suitable for large-scale popularization and application ...
