Guo Wei, Pan Zhongming, Wang Yue-ke · 2010
Presented is a new approach of DOA (Direction of Arrival) estimation based on carry waveform phase for coherent signals, for the purpose of simple algorithm, low processing requirement and low cost. According to the fixity of delay between units and the character of trigonometric function, the formula of DOA estimation for coherent signals is got by deduction in the algorithm. Simulation results show that the precision of the algorithm is as high as Space Smooth algorithm, simpler than Space Smooth algorithm and easily used to engineering application.
