  • Tracking system and method employing multiple overlapping sensors
    Patent number: 6873251
    Abstract: A tracking system and method of estimating position and velocity of an object are provided. The tracking system includes first and second sensors for sensing an object in first and second fields of view, respectively. The first and second fields of view partially overlap to provide an overlapping coverage zone. Each of the sensors measures range and range rate of the object. The system further includes a controller for estimating position and velocity of the object as a function of the measured range and range rate signals, without requiring sensing of the azimuth angle of the object.
