Intention Estimation of Adversarial Spatial Target Based on Fuzzy Inference

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