Accurate Near-Field Signal Direction-of-Arrival Estimation Based on Signal Phase Match Algorithm
Sun Jin-cai · Acta Armamentarii · 2009
The reason,why precision of the near-field signal direction-of-arrival(DOA) estimation is lower,was analyzed based on signal phase match(SPM) principle,the method of accurate near-field signal DOA estimation was proposed based on the principle.The simulated results show that the method has sharp directionality,high resolution and directional precision,and simple calculation.Correctness of the method was verified by the anechoic pool and field tests.The method can improve the precision of near-field signal DOA estimation effectively.
