The problem of estimating quasi-continuous radio signal parameters from low-altitude and low-size moving objects is considered. Methods and conditions for improving the accuracy of spatial coordinate estimates of objects are investigated. The aim of the work is to increase the efficiency of radio systems for observing low-altitude and low-size moving objects. The study is carried out by mathematical and computer modeling of radio signal models and estimating their parameters. It has been shown that the accuracy of estimates can be improved by taking into account the sphericity of wave front. Comparative evaluation of radio system operation efficiency in signal processing in frequency and time areas is given. The simulation results are given. The applied focus of the work is the algorithmic support of radio systems for protecting small territories from low-altitude moving objects.
Key words: radio signals, parameter estimates, mobile low-altitude objects, mathematical and computer modeling.
