摘要：
This paper presents a weighted least squares algorithm for passive localization using Time Difference of Arrival in multipath scenarios. The algorithm is based on the direct or one-step approach for position estimation using distributed sensors and requires no knowledge about the number of received multipaths, the transmitted signal or the transmit time. Delayed signal paths arriving due to multipath propagation are considered and treated as interference to the localization problem. Simulation results show a better and more robust performance of the algorithm, compared to conventional two-step localization algorithms.
