Abstract:
We consider a position estimation system for targets that exist in near wide area. The system has multiple sensors and estimates position using multiple receivers. Previously, receivers arranged in a straight line would generate a large position error in the direction of the line. In order to reduce this error, we herein propose a novel estimation algorithm using the directivity information of the transmitter. The proposed system uses the directional emission of an array of antennas in a transmitter. In the present paper, the error characteristic to be solved is introduced. The proposed algorithm is then presented. Finally, the error reduction performance is demonstrated through computer simulations. The obtained results indicate good error reduction performance.
