摘要： A 3D rendered image of a radar-scanned terrain surface is provided from a radar return signal from the surface, wherein the return signal includes data indicative of azimuth, elevation, and range of a radar-illuminated area of the surface. The data are processed for transformation into X, Y, and Z coordinates. The X and Y coordinates corresponding to each illuminated area are triangulated so as to create a mesh of triangles representing the terrain surface, each of the triangles in the mesh being defined by a vertex triplet. 3D imaging information (grey scale shading and/or coloring information) is added to each triangle in the mesh, based on the amplitude of the radar return signal from the coordinates represented by each vertex in the triplet and the value of the Z coordinate at each vertex, so as to form the 3D rendered image.

摘要： A method and system for creating a precision approach for an aircraft to a position on the ground from a location above the ground is disclosed. The system comprises a display unit onboard the aircraft that displays a digital moving map, a database onboard the aircraft that contains digital terrain elevation data and obstacle data, a global positioning receiver that identifies the in flight position of the aircraft and an input device used to select the position on the ground displayed on the digital moving map. A processor that is also onboard the aircraft is communicably linked to the display unit, the database and the global positioning receiver. The processor generates the digital moving map on the display unit from the digital terrain elevation data and obstacle data and creates an approach derived from global positioning system data for the aircraft to the position on the ground selected on the digital moving map based upon the in flight position of the aircraft.

摘要： The invention concerns a method for producing from passive sonar data operational images interactively controlled by the operator continuously according to operational requirements and compatible with information requirements in real time. The invention is characterised in that it uses a method for representing a multidimensional data field on a display screen (14) which consists in using the screen co-ordinates for two dimensions of data and three colour perception components among luminosity, hue and saturation for three other dimensions of said data, to produce bearing-time, azimuth-time, or frequency-time (circulating lofar) or frequency-bearing with representation of frequencies by hue or interactive filtering.

摘要： The invention pertains to an on-board radar equipment as part of the avionic system in an aircraft, said equipment providing a two-dimensional representation of the radar data from an area located upstream relative to the flight direction. The inventive radar equipment is an upstream sighting radar which gives of the radar data a high resolution and map-consistent representation from above in accordance with its basic operating mode resting upon the SAR(synthetic aperture radar)-based processing principle or an equivalent principle. A digital image processor enables a purely geometrical conversion of the map-consistent representation from above provided by said radar equipement into a corresponding image with a centered perspective projection and with a quasi-pilot vision. The invention is used when aircrafts and helicopters fly under bad visibility conditions or with no visibility at all.

摘要： Disclosed is a three-dimensional radar apparatus comprising a radar transmitting/receiving unit (14), a three-dimensional polygon-generating unit (16), and a three-dimensional graphics unit (18), wherein a radar transmitter/receiver (20) outputs signals concerning orientation information, distance information, and reception intensity information on the basis of a radio wave reflected from a target, and a scan converter (22) is used to convert the signals concerning the orientation information, the distance information, and the reception intensity information into two-dimensional radar image data composed of two-dimensional rectangular coordinates and brightness information of each of picture elements. The two-dimensional radar image data is also inputted into the three-dimensional polygon-generating unit (16) to perform polygon-generating processing on the basis of the two-dimensional rectangular coordinates and the brightness information of each of the picture elements. Three-dimensional radar image data is prepared in the three-dimensional graphics unit (18) on the basis of obtained polygon-based information, and it is accumulated in a frame memory (24). Thus, a three-dimensional radar image is displayed on a display device (26).

摘要： Non-contact type wave signal observation apparatus (511) takes measurements of electromagnetic waves received on an observation plane and performs hologram reconstruction calculations to reconstruct characteristics of the corresponding electromagnetic wave information at points in the observed space. The invention provides a display for displaying complex three-dimensional data such as interference data of electromagnetic waves produced by such non-contact type wave signal observation apparatus. The complex data is converted (513) from orthogonal co-ordinates to polar co-ordinates, the phase information is converted to hue information in a hue converter (514) and the amplitude information is used to modulate (515) the brightness of the displayed signal; corresponding colour signals are displayed on a colour display unit (516).
