Analysis of the Degradation in Source Location Accuracy in the Presence of Sensor Location Error

It is well known that sensor location uncertainty can seriously deteriorate the source location accuracy. In this paper, we provide the analysis of how much degradation the source location accuracy is expected to be with respect to the amount of sensor location error. We first derive the source location MSE when the estimator assumes no sensor location error but in fact there is. Then, the CRLB is evaluated and compared with the one without sensor location error. The analytical results allow us to decide whether a new algorithm to account for the sensor location error is necessary to improve the source location accuracy.
