Abstract	For the interferences suppression of a large-scale antenna array after a subarray configuration (SC), a generalised sidelobe canceller (GSC) weighting approximation at irregular subarrays algorithm is presented. First, the SC is obtained by particle swarm optimisation. Then, digital weights of the second-class subarrays and also the analogue weights of the elements and first-class subarrays are optimised in two steps by convex optimisation to approximate GSC weights to the maximum extent, which are directly applied at the element level of the whole array. Simulation results are presented that prove that the proposed algorithm achieves better performance of anti-jamming than direct GSC weighting at subarrays.
