Abstract :
Source location accuracy can be dramatically degraded by the inaccuracy in the sensor positions. The sensor position errors need to be taken into account in order to improve the source location estimate. This paper presents an algorithm based on the Taylor-series technique to estimate the location of an emitting source in the presence of random sensor position errors, where the data measurements are angle-of-arrivals (AoAs). The proposed algorithm jointly estimates the source and sensor positions iteratively by using Taylor-series linearization. Simulation results indicate that the proposed method approaches the CRLB accuracy for both near-field and far-field sources
