Abstract: An aircraft enhanced vision system includes an electromagnetic sensor comprising at least one group of transmitters and at least one group of receivers. The electromagnetic sensor includes a waveform generation assembly powering each transmitter in order to generate the transmitted signal and a signal capture assembly to capture the signal received by each receiver after reflection off of the ground. The transmitters are distinct and spaced apart from the receivers, being arranged so as to form at least one virtual transmitter/receiver network extending in an elongation direction perpendicular to the observation direction from each transmitter/receiver combination between the group of transmitters and the group of receivers.

Abstract: A device including a holder and a transmitter supported by the holder is provided. The transmitter is capable of transmitting an electromagnetic signal toward the surface any transmission frequency (Fe). The device also includes a receiver for receiving a signal reflected on the surface. The device also includes a guide assembly for guiding the movement of the holder to move the transmitter and the receiver across from the surface, tangentially relative to the surface. The device also includes an extraction unit for extracting, in the signal received by the receiver, a shifted frequency component of the transmission frequency resulting from a local impedance variation of the surface. The extraction unit produces an extracted signal representative of the state of the surface from the shifted frequency component.

Abstract: The aerial comprises an element (20) capable of radiating or receiving an electromagnetic field, a conductive plane (22), and an anisotropic composite 24, formed by a stack of alternate ferromagnetic and electrically insulated layers. These layers or film are perpendicular to the conductive plane and to the electrical component (E) of the radiated or received field.
