Abstract
Simulation modeling for the verification of the assessment of radar parameters of air mass movement
Incoming article date: 05.10.2025Verification and debugging of algorithms and related software that implements the search for such dangerous phenomena for aircraft flights as wind gusts and turbulence areas can be implemented in radar signal simulators, including using the concept of accessing databases storing test wind fields by coordinate components. The practical value of this approach is to minimize the number of expensive flight tests in difficult weather conditions. After implementing database data interpolation, continuous fields can be obtained, including predicted radar parameters, the processing of which, depending on the changing parameters of the locator: beam width, probe pulse duration, leads to different estimates, including the measured parameters of the movement of air masses. This article describes an approach to simulation modeling that makes it possible, by generating radio signals, the primary source of which are continuous interpolated functions of air mass motion parameters, to obtain either averaged radial velocity values in resolution elements or its standard deviation. As a result, it allows us to test signal processing algorithms for detecting wind shifts or turbulence in weather navigation radars. The results of verification of the procedure for processing radio signals generated using the proposed approach are presented, confirming the correctness of the formation and detection of simulated fields of turbulent regions.
