Abstract

A method is offered to estimate trajectory parameters influence upon the attitude of an aerodynamic object. The technique is based on minimization of mean square differences over n subsequent attitude estimations, packed out from radar and optical channel, with respect to unknown parameters of the model. It is shown the probabilistic criteria appear equivalent to minimum mean square vector difference of n attitude estimations according to registration channel functioning principles. The model is linearized with respect to its parameters. This technique allows using pseudo inversion of matrix to solve the problem. Mathematical expression is obtained to compute estimations of model parameters. An algorithm is offered for implementation of estimation process. The algorithm consists of one step and estimates for n samples simultaneously. The model is ready to use for various radar signal processing problems.
