A High Performance Beam Forming Method Based on The Secondary Combination Array

1649

The paper has proposed an adaptive beam forming method based on the secondary combination of the array elements. After the partition of the array, the adaptive beam is achieved by the sub-array for the desired signals and the jamming signals, and the jamming signals are restrained deeply by the pattern of the sub-array. The outputs of the sub-arrays are combined secondarily as the array elements. The pattern of the secondary combination array is synthesized to compensate the pattern of the sub-array oppositely. The simulation for the uniform linear array (ULA) proves the effectiveness of the method.
