Vehicle Following Technique Based on Kalman Filter

This paper describes the Kalman filter to establish a moving model.This model can be used to track one or more moving objects.We give the state equation and the measure equation for one object.And more,we describe the calculation ways and the experiment result.We have experimented the following technology at 120 km/h on highway in Sichuan Province of China.The result shows that the algorithms can work perfectly.
