Abstract: The invention relates to a MIMO imaging radar system. The system comprises transmission channels (Ve1, VeM), reception channels (Vr1, VrN), and co-located radiating elements (ERe1, EReM, ERr1, ERrN) forming a two-dimensional antenna array. Each radiating element (ERe1, EReM, ERr1, ERrN) has a predefined instantaneous field of coverage. Each radiating element is formed by a plurality of p radiating sub-elements (SeElt1, SsEltp) distributed in at least one of the two dimensions of the antenna array. The radar comprises a plurality of electronic steering modules (MDe1, . . . , MDrN). Each electronic steering module is connected to one radiating element. Each steering module is configured to apply a steering command (Cmd) between all the radiating sub-elements (SeElt1, SsEltp) of a given radiating element. The steering command (Cmd) is identical from one radiating element to the next, so as to move the field of coverage of each radiating element in the same direction.

Abstract: A proximity radar method for a rotary-wing aircraft includes a sequence of phases T(k) of steps. In a first phase T(1), the electronic computer of the radar system computes unambiguous synthetic patterns on the basis of a first activated interferometric pattern M(1) of N unitary radiating groups. In the following phases T(k) of steps, executed successively in increasing order of k, the electronic computer computes synthetic patterns on the basis of interferometric patterns M(k) of rank k, wherein the N unitary radiating groups of a series deviate simultaneously in terms of azimuth and in terms of elevation as k increases, and establishes maps of rank k of the surroundings in terms of azimuth distance/direction and/or elevation distance/direction cells wherein the detected obstacle ambiguities, associated with the network lobes, are removed by virtue of the map(s) provided in the preceding phase or phases.

Abstract: A detection method implementing an FMCW waveform is provided, the emitted waveform is formed of a recurring pattern of given period Tr covering an emission frequency band of given width B, each pattern being divided into a given number P of sub-patterns of duration Tr/P covering an excursion frequency band ΔF=B/P, the sub-patterns being mutually spaced by a frequency interval equal to ΔF. The radar performs: a first distance-compression processing operation carrying out a low-resolution distance compression at the scale of each recurring pattern on a fraction B/P of the emission band of width B corresponding to the frequency band covered by each of the sub-patterns; a Doppler processing operation on a given number N of successive recurrences so as to form P ambiguous distance-Doppler maps of low distance resolution, the maps being segmented into various speed domains; a second distance-compression processing operation of resolution that differs depending on the speed domain to which the relative speed of the target with respect to the radar belongs.
