Abstract

This paper proposed a novel calibration algorithm for sensor position errors of moving sensors by using calibration emitters. The algorithm presented is based on time difference of arrival (TDOA) measurements received by sensor network with sensor position error. Firstly, the linear relation between sensor position errors and TDOA measurements is derived by Taylor's series expansion. Then, a linear minimum mean square error (LMMSE) estimator of sensor position errors is derived based on the linear model. At last, on the assumption that sensor position errors of moving sensors are steady in a short time, a sequential LMMSE algorithm for sensor position errors estimation is proposed. Simulation results demonstrate the good performance of the proposed algorithm.
