The requirement to increase the accuracy of the generated estimates of the parameters of the movement of air targets (AT) with their multi–purpose support, which are necessary for the implementation of guidance methods and comprehensive information support, is due, on the one hand, to the need for their constant formation, on the other hand, to the rare arrival of measurements formed as a result of radar contact with the AT due to the need to control the rest, free from serviced space goals. The rare receipt of measurements leads to a decrease in the accuracy of the generated estimates.

The purpose – investigate, using the example of a rangefinder channel filter, an algorithm for multi-purpose AT tracking synthesized on the basis of analog-discrete Kalman filtering equations, taking into account, in the interests of improving the accuracy of the estimates generated, the changing signal-to-noise ratio at the input of the radar receiver at different intervals of measurement receipt.

Based on the analysis of the simulation results, the possibility of increasing the accuracy of estimating the coordinates of the state in the filter of the rangefinder channel synthesized on the basis of the equations of analog-discrete Kalman filtration, by taking into account the energy of the re-reflected signal that increases during the approach of the interceptor with the AT.

The implementation of the proposed approach will increase the potential accuracy of the estimated coordinates of the state in the multi-purpose tracking mode of the AT in onboard radar systems.
