  • Passive location technology has been applied broadly these years. Taylor expansion method was commonly used by the traditional multi-station passive location system. A new method of time difference of arrival(TDOA) passive location with multi-station based on weighted matrix was presented. When the stable carrier being included in a target-s emission signal, the noise characteristics equations was analyzed using the conventional time-domain correlation method after the carrier was tracked. The model was constructed with the weighted matrix of the distance difference observations among a number of stations, thus the high accuracy location being obtained by employing the weighted matrix. From the simulation, it can be proved that under the same condition, the position results using presented method are more accurate than the traditional Taylor expansion method, improved by about 30% in best cases. This method is an effective method for multi-station passive location, particularly for mobile observation stations.
