    Abstract: A transceiver device and associated antenna are disclosed. In one aspect, the transceiver device combines first and second transceiver modules with a transceiver capability including a substantially planar radiating element and including a central point. Each transceiver module is a transceiver module coupled with the transceiver capability so as to excite a pair of excitation points of the radiating element, the excitation points of one pair being arranged symmetrically relative to the central point of the radiating element. The first and second transceiver modules respectively excite a first pair of excitation points arranged in a first direction of the radiating element and a second pair of excitation points arranged in a second direction of the radiating element, the first and second directions being mutually orthogonal.

    Abstract: This method involves, for an array of at least two antennas pointing in different directions and the respective radiation patterns of which overlap one another, each antenna including at least two radiating elements so as to be able to work in a first operating mode associated with a first radiation pattern (Δ) and according to a second operating mode associated with a second radiation pattern (Σ): acquiring, for each antenna, a first signal (SΔi) corresponding to the first operating mode and a second signal (SΣi) corresponding to the second operating mode; determining, for each antenna, an opening half-angle (ρi) of a cone of possible directions of incidence from the amplitude of the first and second signals; calculating the bearing angle (Θ0) and/or the elevation angle (φ0) of the direction of incidence by intersection of the cones of possible directions of incidence determined for each antenna.

    Abstract: A radar, flying device including such a radar, processing method in a radar embedded in a flying device and associated computer program are disclosed. In one aspect, the radar includes a transceiver antenna including a plurality of radiating elements configured to transmit and receive an electromagnetic wave. The radar includes an antenna gain control unit, by activating/inhibiting radiating elements, in transmission and/or reception configured to keep the reception level of an electromagnetic wave below a determined threshold below the saturation zone of the antenna, as well as by activating/inhibiting radiating elements in reception, configured to compensate the amplitude variation of the ground/sea clutter, over the duration of the reception.

    Abstract: An electronic-scanning antenna composed of radiating elements each forming an active channel in which the signals arising from the channels are grouped together to form deviometry signals, each deviometry signal forming a deviometry channel, and are grouped together according to sectors to form a sector-based signal forming a sector channel, a computation-based beam being formed on the basis of the signals arising from each of the sectors, the method comprises the following steps: measuring the response to a calibration signal of each active channel at one and the same time on the sum deviometry channel and on the sector channel to which it belongs, the responses on the sum channel to obtain the calibration of the sum channel; computing, for each active channel, the disparity between the mean of the responses measured on the sum channel and the mean of the responses measured on the sector to which it belongs; in the operational phase, forming the beam by computation on the basis of the measurements of the signals arising from the sector channels calibrated with the calibration obtained for the sum channel, and correcting the computation of the beam as a function of the disparity.
