Abstract
Sensor location uncertainty of array degrades severely the performance of eigenstructure based direction finding system. A new calibration method of sensor location is presented with three far field sources whose directions are not known accurately. A signal subspace based iteration algorithm for sensor location calibration is developed and its convergence to the global optimal point has been shown. The guide line for selecting directions of calibrating sources is given. Simulation results illustrate that the new method is successful and practicable.
