Abstract: This article presents a passive DOA jointed TOA location algorithm and the corresponding analysis of the location accuracy. A set of simulations are implemented to compare the DOA jointed TOA, DOA, and TOA location algorithm. Results show that the proposed algorithm has the best performance in terms of both location accuracy and system requirement. Overall speaking, it is a practical passive location method. -
