摘要

Direction finding by MUSIC algorithm in noncooperative passive detection system is proposed. Basing on the method the array error is corrected by instrumental sensor method (ISM). In the method, firstly, the correlation signals of array received signals and the frequency-shift signals of direct signal are obtained; secondly, the signals near to estimation delay of correlation signals are selected as new received signals of the array; finally, MUSIC algorithm is used to find object's direction. It is proved that when the new received signals' length is 1, the method has highest estimation precision. Simulation result shows that theoretical derivation is correct and the method is effective.
