The sensor position errors calibration algorithm based on auxiliary sensor is studied in this paper. The cross array model and the sensor position error model are analyzed in detail. A new method based on auxiliary sensor is proposed to solve sensor posi- tion errors calibration problem. The result indicates that the algorithm is effective, and the high precision can be achieved with sim- ple calculation.
