Intention Estimation of Adversarial Spatial Target Based on Fuzzy Inference

Abstract

Estimating the intention of space objects plays an important role in aircraft design, aviation safety, military and other fields, and is an important reference basis for air situation analysis and command decision-making. This paper studies an intention estimation method based on fuzzy theory, combining probability to calculate the intention between two objects. This method takes a space object as the origin of coordinates, observes the target’s distance, speed, relative heading angle, altitude difference, steering trend and etc., then introduces the specific calculation methods of these parameters. Through calculation, values are input into the fuzzy inference model, and finally the action intention of the target is obtained through the fuzzy rule table and historical weighted probability. Verified by simulation experiment, the target intention inferred by this method is roughly the same as the actual behavior of the target, which proves that the method for identifying the target intention is effective.
