DOA Estimation Algorithm of Multipath Signals Based on Temporal Data Block Smoothing
Cheng Qing · Radar Science and Technology · 2010
To solve the problem of DOA estimation for multipath signals in low-angle environment,an algorithm,which is called TDBS,is proposed in this paper.By using data block smoothing,the TDBS algo-rithm based on the declined character of multipath signals can reduce the computational complexity of TS.The proposed method does not suffer the reduction of the effective array aperture size and is not limited by the array configuration.In addition,the performance of the TDBS is better than the spatial smoothing method when the velocity of the source reach the certain degree.The correctness and effectiveness of the proposed method are verified by the computer simulation results.
