First Claim
Patent Images
1. A method for displaying target vehicle position information comprising the steps of:
- providing a plurality of sensors, each contributing traffic information data for each of a plurality of target vehicles;
fusing the traffic information data from each of the plurality of sensors to calculate a derived target position for each of the plurality of target vehicles;
displaying the calculated derived target position of each of the plurality of target vehicles as a singular target on a display screen; and
displaying a position report of a target vehicle from each of the plurality of sensors with a maximum error bound for each position report.

Abstract
A system and method for displaying target vehicle position that combines the data available from a plurality of surveillance sensors. Data from the plurality of sensors is fused to calculate a composite target position and a projected track for each vehicle within the range of the sensors. The composite data is also used to calculate a boundary of certainty for both the position and the projected track. The position, projected track and the boundaries of certainty for each target vehicle can be displayed on a display screen.
