Investigation of Conditions for Detecting False Windshear Areas in Weather Radar for Low-Altitude Flights of Small Aircrafts

Improving the efficiency of solving problems of navigation and safety of small aircraft at low altitudes can be achieved by equipping aircraft with radars that warn of dangerous weather conditions on the flight path. This is especially important when such a weather phenomenon is a windshear, which is dangerous when flying at low altitudes, is short-lived and occurs suddenly. In this paper, we present algorithms for secondary signal processing for evaluating spatial criteria that allow us to determine whether the wind shear region detected by the onboard coherent pulse-Doppler weather radar is dangerous for flights.
