The performance of high-resolution algorithm will degrade badly in the presence of sensor position errors. To deal with this problem, a mew method for array calibration using particle swarm optimization (PSO) algorithm is proposed. This new method has no requirement for calibration sources while the sensor position errors as well as the direction-of-arrivals (DOAs) of the incident signals can be estimated simultaneously. Computer simulations are conducted to show the validity and feasibility of the proposed method. (3 pages)
