Criterion and Methodology Selecting Fixed Parameters of Algorithms for Tracking Aerial Objects

Abstract

Multifunctional radars allow tracking several air objects at the same time in the time division mode. Tracking mode of various air objects in the radar is provided by radio tracking systems in terms of range, radial velocity and angular coordinates, which, as a rule, use digital systems for processing and filtering spatial coordinates, the algorithms of which are synthesized on base of adopted model the air objects movement and model of observation. The paper proposes a method for selecting apriori uncertain characteristics of external influences, which are used in models of air objects movement and models of observations for synthesis of tracking algorithms with fixed parameters based on the criterion of minimum average losses in tracking accuracy. The results of solving problem choosing characteristics one of variants the model of maneuvering air objects movement for tracking algorithm in range are presented.
