Differential Correction Applications to the Estimation of Non-Cooperate Targets Motion

Accurate measurement of relative kinematic parameters is necessary for the surveillance and companion flying for non-cooperate targets. The relative distance can be estimated accurately when tracing aircraft maneuver with specific path. Differential correction method is used in relative distance estimation by line-of-sight (LOS) angle sequence. Numerical simulations show that this approach presented in this paper can effectively reduce the measurement error of the relative kinematic parameters.
