Based on parameterized model of target flight orbit, this paper presents an algorithm to estimate target range and other location and velocity via infrared sensor, according to this, target threat degree and target identity can be discriminated. Simulation calculation confirms that this method is more accuracy, and depends less on a opriori knowledge of target location initial value. This algorithm can be used for target motion parameter estimation in other measure system.
