    摘要: An active imaging system for imaging a target is described. The system includes a transmitting unit, a receiving unit, an antenna arrangement coupled to the transmitting unit and/or the receiving unit via a front end unit, and an image processing unit coupled to the receiving unit. The system also includes a control system coupled to the transmitting unit, the receiving unit and/or the image processing unit for controlling operation thereof. The antenna arrangement includes at least one rotating antenna synthetically forming a circular antenna. The image processing unit is configured for creating an image of the object by employing a synthetic aperture radar imaging algorithm.

    摘要: This invention relates to the field of sea surveillance and to the detection of drifting slicks of pollutants. The method according to the invention uses rotating-antenna pulse radar to implement two separate processing modes: - one conventional operating mode in which the radar carries out the detection, positioning and trajectory analysis of the objects (11) situated in the region of space that is scanned, - a mapping-type operating mode, in which the radar maps two bands of the surface (12) extending laterally in relation to the forward-moving direction of the aircraft, while producing the high-resolution image of the scanned areas, the two operating modes being implemented for different angular sectors at each rotation of the antenna. The invention applies in particular to radar systems equipping aircraft responsible for maritime and coastal patrol missions.
