An Airport Surface Detection Radar (ASDR) including a transmitting antenna (116), a transmitter (110), which transmits a substantially linearly frequency modulated CW signal via the transmitting antenna (116), a monopulse receiving antenna (118) and a monopulse receiver which receives at least one response from a target on an airport surface via the receiving antenna (118), generates azimuthal sum and difference signals and determines the position of the target responsive to the instantaneous sum and difference signals and orientation of the antennas.

La présente invention concerne un radar de surveillance des mouvements de surface d'aéroport. Ce radar est constitué d'une antenne d'émission (116), d'un émetteur (110) émettant via l'antenne d'émission (116) un signal modulation de fréquence à onde entretenue sensiblement linéaire, d'une antenne de réception monopulsée (118), et d'un récepteur monopulsé recevant via l'antenne de réception (118) au moins une réponse en provenance d'une cible se trouvant sur la surface de l'aéroport. En l'occurrence, ce radar génère des signaux de sommes et de différences azimutaux puis détermine la position de la cible en prenant en considération non seulement les signaux de sommes et de différences, mais également l'orientation des antennes.
