The concept of target logical model was defined in this article. According to target logical model, the target attribute distribution function and the target attribute matrix were established, and the target identification method was proposed based on logical model. The parameters of the target logical model such as target height, target speed and RCS were used, and three groups of the target parameter sample were chosen for simulating logical model identification. The simulation results show that this method has many characteristics such as simple principle, easy realization, and high credibility and so on.
