Popis: Background. The current stage of aviation development is characterized by a steady tendency to increase requirements for the tactical and technical characteristics of aircraft, including navigation systems. A natural consequence of this tendency is the increasing role and importance of radar sensors of navigation information. These include radio altimeter systems (RAS), which measure the altitude and components of the velocity vector in a linked coordinate system. At present, an urgent task is to improve the accuracy of RAS characteristics over heterogeneous complex surfaces. Materials and methods. Considers the following methods for solving the problem: adaptation of algorithms for estimating the components of the RAS velocity vector to the underlying surface by changing the pulses time depending on the value of the aircraft flight altitude; adaptation of algorithms for estimating the components of the RAS velocity vector to the underlying surface by changing the antenna system configuration; adaptation of algorithms for estimating the components of the RAS velocity vector to the underlying surface by switching the RAS frequency. Results and conclusions. Methods usage will significantly improve the tactical and technical characteristics of both existing RAS and new developments, and will reduce the time of development.
