DOA Estimation Algorithm Based on FFT in Switch Antenna Array

摘要：

An algorithm for fast DOA estimation in single-channel antenna array is proposed for the high complexity and low timeliness of the present algorithms. This algorithm applies the spatial FFT of multi-channel antenna array to single-channel antenna array. It takes the switching time into operation to construct the new transformation function, which can be utilized to operate spatial FFT to the sampled data of single-channel antenna array directly. Based on this, the SAA-FFT algorithm fitted for single-channel antenna array is proposed. The theoretical analysis and simulation results demonstrate that the algorithm is effective.
