Investigation of the Characteristics of a Modified Algorithm for Tracking an Aerial Target in Transit

In the article, using the example of a rangefinder channel filter, an algorithm for filtering the motion parameters of an airborne target (AT) when escorting it through the aisle is studied, synthesized on the basis of analog-discrete filtering equations, taking into account the changing signal-to-noise ratio at the input of the receiver of the on-board radar system (radar), at different values of the filter parameters. Based on the analysis of the simulation results, it is established that it is possible to increase the accuracy of estimation and prevent the divergence of filtering the coordinates of the state in the rangefinder channel filter by taking into account the energy of the reflected signal increasing during the approach of the interceptor to the AT. The implementation of the proposed approach will increase the potential accuracy of the estimated coordinates of the state and prevent the divergence of filtering in the rangefinder channel when the interceptor radar is operating in the escort mode on the passage.
