Because of the influence of the complexity environment and noise jamming, target identification is uncertain in the flight-test examination. To enhance the preciseness rate in target identification, target characteristic information is extracted based on the measurement of the target by the sensor. The subjection degree relative to the reference target in the target storage is calculated via maximal subjection degree principle. The trusting degree of the sensor is gained via D-S theory. Fusion target identification result is calculated finally. Target character can be identified efficiently under the complex test flight environment via this method. The method is simple, credible and practical.
