Abstract :
We focus on the reduction of the positioning errors on radar network systems. The radar network systems can achieve reliable detection and wide observation area by using multiple sensors. However, the accuracy of the positioning depends a great deal on the arrangement of the sensors. For example, if receivers were arranged on a straight line, the large error in the same direction of the line is generated. This is because the target is observed from only one direction, which is called as one side observation. In order to reduce the error, we proposed novel algorithm which uses not only a direct path but also reflected multipath. In this paper, we will introduce our method and present estimation performance by computer simulations.
