Method for observing an environment with simultaneous active and listening modes and associated devices

Abstract

Method for observing an environment with a simultaneous active mode and listening mode and associated devices The present invention relates to a method for observing an environment comprising the successive implementation of an active mode, each implementation comprising the steps of: - emission of a radar pulse by the radar (16), - reception of echoes of the radar pulse emitted in a radar reception band, the echoes forming at least one emission sub-band of the reception band, the reception step also comprising the reception of a sub-band allocated to a listening mode in the same reception band, each emission sub-band being associated with a respective emission domain and each sub-band allocated to the listening mode being associated with a respective listening domain, each domain being characterized by an observation direction and an observation frequency, each listening domain being different from each emission domain.Figure for the abbreviation: figure 1.
