摘要
The invention relates to a detection device, comprising a parabolic mirror (1) and several radiation detectors (2-5). The detectors are placed in the focal plane (O, X′-X, Y′-Y) of the mirror with respective spacings in a common fixed direction (Y′-Y). The detection device further comprises a selector system, connected to each of the detectors (2-5), embodied to successively select each of the detectors and to transmit a received signal from the selected detector. The separations of the detectors (d2-d5) are selected such that a gain diagram, for the reception of said device, has a gain minimum, between two successive gain maxima, each corresponding respectively to one of the detectors, of less than 3.0 dB less than said gain maxima. Such a device permits a sweeping of a zone with several adjacent sub-sweeps from a machine overflying said zone.
