The multisensor tracking system with the airborne sensor to mitigate the effect of cross-range errors

In order to reduce the angle component of measurement noise (cross-range errors), we propose a multisensor tracking system with an airborne and a stationary sensor. The airborne sensor is a phased array sensor which an aircraft carries. In the proposed system the airborne sensor moves in order to keep the pencil beams from the airborne and stationary sensors orthogonal. Therefore the proposed system minimizes the cross-range errors and a high tracking quality could be obtained. Simulation results are given for a comparison of the tracking performance of our proposed system with that of conventional systems
