RADAR INFORMATION DISPLAY METHOD Russian patent published in 2016 - IPC G01S7/12 G01S13/89 

FIELD: radar.

SUBSTANCE: invention relates to methods of displaying radar information on screens of radar station displays. Said result is achieved by receiving, by a radar station, radio signals reflected from objects, converting signals received from objects in digital form, displaying converted signals on a flat screen in form of light marks on z0y plane, and azimuth and range scales in form of crossing lines also on z0y plane, wherein screen plane z0y is virtually inclined in planes z0x and y0x, mark from an object is transferred in parallel to axis 0z and is indicated above inclined plane of screen by a value of height of object and converted to virtual mark, to said virtual mark is added a dash in parallel to axis 0z, with a scale of height on dash, in direction of inclined plane of screen, dash of height by end rests in virtual mark from an object, and by second end rests on point of actual values of azimuth and range of object on inclined screen, on which is displayed point with values of azimuth and range of object relative to point of radar station, and inclined plane of screen displays either earth horizon plane or plane of earth's surface relative to point of radar station (depending on operating mode of radar station), wherein length of dash of height, with a scale of height, characterises height of object over horizon or above ground level (depending on operating mode of radar station). Speed and direction of movement of object in space are displayed by dash-speed vector, beginning of which rests against displayed virtual object mark, and direction of dash-velocity vector characterises direction in space relative to point of radar station, and also on dash-velocity vector a speed scale is applied, which characterises value of speed of object in space, and plane, which characterises earth's surface, is displayed as part of spherical surface, radius of which is proportional to radius of earth at point of radar station, and perimeter of spherical surface is limited by radar detection range, while radius of spherical surface is rapidly changed according to operator request from proportional radius of earth to infinity, thereby turning curvature line of earth into straight line, that is into a horizon line, and inclination of planes z0y and y0x is varied from 0 to 90 degrees, thereby converting isometric image of space observed by radar into a Cartesian image, and pseudo-volumetric four-dimensional image into three-dimensional image plane, that is into a three-dimensional indicator azimuth - range - speed or into three-dimensional indicator range - height - speed, and plane, which characterises earth's surface, is turned at desire of operator about axis, crossing point of radar station and perpendicular in this point to plane of earth's surface. Near point of reflecting object, at desire of operator, model-portraits objects taken from database of radar station are displayed, configuration of which is proportional to configuration and size of detected objects.

EFFECT: technical result is improved reliability and information value of radar information on parameters of aerial, surface and ground objects.
