Antenna array element position error detection method in interference environment

Provided is an antenna array element position error detection method in an interference environment. Aiming at the purpose of detecting antenna array element position errors by utilizing known correction signal direction and an antenna array receiving signal in the interference environment, an orthogonality relation between an actual antenna array direction vector corresponding to the correction signal direction and noise subspace is utilized, a constrained relation that the amplitude of all elements of a compensation vector is equal to one, and a first element of the compensation vector is equal to one is utilize, the compensation vector corresponding to the antenna array direction vector of the correction signal is determined from a received signal vector of the interfered of the antenna array in an iterative method, the detection of the array element position errors of the antenna array in the interference environment can be achieved by utilizing relation between phase positions of elements of the compensa
