Abstract :
We propose an interpolation-based array calibration method for near-field source localization in this paper. A received signal model is developed in presence of imperfect effects in a sensor array. The position-dependent errors are modeled in a diagonal correction matrix. An interpolation-based approach is then proposed to calibrate the array response with a small number of measurements. This approach allows us to improve the efficiency of array calibration for source localization in near-field situation.
