Abstract :
Target passive locating and tracking is a typical application for UAV In this paper, the state space model of airborne bearing-only tracking was firstly introduced. A typical flight trajectory of UAV was simulated by integrated navigation based on the Federal Kalman Filter. And then, according to the navigation parameters from the flight trajectory, an Air-to-Sea passive locating and tracking were simulated based on UKF. The result shows that the CEP of the locating precision is less than 50m. Finally, Some factors which seriously affect the locating precision are discussed.
