A mathematical model that uses a differential approach to assess detection quality in a wide range of target Doppler velocities is proposed. Based on the model, the authors consider complex efficiency of MTI and MTD application in processing ship survey radars when detecting aerodynamic targets in the conditions of natural passive interference, taking into account internal destabilizing factors of station. The aim of the article is to develop a mathematical model that uses a differential approach to assess detection quality in a wide range of Doppler target speeds, and based on it, to comprehensively assess the efficiency of MTD and MTI application for the protection against hydrometeors in ship-based airspace survey radars. When considering, we limited ourselves to typical operating frequency ranges and common methods of frequency selection. A rain cloud of hydrometeors of medium intensity is accepted as passive clutter
