Development of a modern type of display of meteorological navigation information on on-board radar indicator display

The task of improving the safety of piloting small aircraft flying at altitudes not exceeding the lower cloud limit depends, among other things, on the completeness and speed of intuitive perception of meteorological navigation information, which makes it possible to choose flight routes in advance in areas with difficult weather conditions. At the same time, the visualization of this information in aircraft intended for international flights is limited by the accepted standard data transmission protocols. The limitations imposed on the display of meteorological navigation information, existing solutions for obtaining and displaying more complete data on both spatial coordinates and the degree of danger of atmospheric formations received in on-board radars are analyzed. New visualization approaches have been proposed that increase the information content of meteorological navigation data and focus on obtaining more intuitive images. To investigate the scientific and technical groundwork used in on-board radars to analyze the current meteorological situation, to supplement it with proposals for developing a promising type of display of meteorological navigation information on indicator displays, ensuring continuity according to the hazard criteria adopted in international standards for on-board radar, focused on obtaining more intuitive images. The results of the analysis are presented, confirming the expediency of switching from a flat– two-dimensional form of displaying meteorological navigation information in a pseudo-three-dimensional or three-dimensional form with visualization of additional layers obtained for the current position of the aircraft from vector terrain maps. The performance requirements of the processor implementing secondary processing of radar data before their potential output on the indicator are estimated. The results of the work can be used in meteorological navigation onboard pulse-Doppler radars with optional image output for hybrid visualization.
