Abstract[English]
A radar apparatus (418) for calculating a position of a transponder (408) is disclosed. The distress signal received from the transponder (408) in response to the electromagnetic waves transmitted by the radar apparatus (418), is displayed as twelve bright on the radar screen (504). A transponder distance detection module (602) calculates an actual distance of the transponder (408) and obtains a distance, an azimuth, and a signal level of each bright points, upon detecting the distress signal from the transponder (408). A transponder azimuth detection module (604) calculates an azimuth of the transponder (408) based on a distance, an azimuth, and a signal level of each bright points. A transponder position calculation module (606) is configured to calculate a latitude and longitude of the transponder (408) based at least on the latitude and longitude of the vessel (402), the actual distance, and the azimuth of the transponder (408).[French]
L'invention divulgue un appareil radar (418) pour calculer une position d'un transpondeur (408). Le signal de détresse reçu du transpondeur (408) en réponse aux ondes électromagnétiques transmises par l'appareil radar (418) est affiché sous la forme de douze points lumineux sur l'écran radar (504). Un module de détection de distance de transpondeur (602) calcule une distance réelle du transpondeur (408) et obtient une distance, un azimut et un niveau de signal de chaque point lumineux, lors de la détection du signal de détresse provenant du transpondeur (408). Un module de détection d'azimut de transpondeur (604) calcule un azimut du transpondeur (408) sur la base d'une distance, d'un azimut et d'un niveau de signal de chaque point lumineux. Un module de calcul de position de transpondeur (606) est conçu pour calculer une latitude et une longitude du transpondeur (408) sur la base au moins de la latitude et de la longitude du navire (402), de la distance réelle et de l'azimut du transpondeur (408).
