摘要： The invention relates to an electronic switching device for high-frequency signals. The invention is of particular use in the connection between a microwave frequency antenna and an electronic circuit. This circuit comprises one or two access points designed to be connected to the antenna forming a third access point. In the case of a switch between one access point and the antenna (called an SPST switch), it comprises two switching diodes, one, called a serial diode, being connected in series between the access points and the other, called a shunt diode, between one of the access points and an earth of the device. According to the invention, a first transmission line is placed in series with the shunt diode, a second transmission line is placed in series with the serial diode, a third transmission line is placed at the common point of the first transmission line and of the shunt diode, a fourth transmission line is placed at the first access point, and a fifth transmission line is placed at the second access point. For a switch with three access points, two other diodes and four other transmission lines are added in a symmetrical manner relative to those already described. It is possible to obtain adapted lines having lengths much shorter than λ/4, which makes it possible to improve the compactness of the device while increasing its bandwidth.

摘要： The present invention relates to system for detecting obstacles (13, 55, 56, 57) on the ground (15) onboard a carrier (1). The detection system comprises at least two continuous-wave radars (2, 3, 4). The radars (2, 3, 4) are linked to a system (15) for utilizing the detection data arising from the radars (2, 3, 4). The detection system performs localization of an obstacle (13, 55, 56, 57): along a radial axis (12) between a radar (2, 3, 4) and the obstacle (13, 55, 56, 57), by calculating the distance between the radar (2, 3, 4) and the obstacle (13, 55, 56, 57); along a vertical axis (14) with respect to a radar (2, 3, 4), by calculating the elevation of the obstacle (13, 55, 56, 57) using monopulse deviation-measurement processing. The detection system performs localization of an obstacles along a horizontal axis (18) transverse with respect to a sighting axis (11) of a radar (2, 3, 4), by calculating the azimuthal position of the obstacle (13, 55, 56, 57). The invention applies notably in respect of the detection of obstacles on the ground so as to avoid any collision between a taxiing aircraft and these obstacles.

摘要： The present invention relates to a method for determining the position notably the elevation of a target flying at very low altitude. An electromagnetic detection system extracts the measurement of the elevation on the basis of the amplitude of the interference signal produced by a signal emitted directly by the target and by a signal emitted by the target towards the ground then reflected by the ground towards the radar. Embodiments of the invention can notably be used within the framework of the guidance of drones in the final landing phase.

摘要： Disclosed is a method for the discriminating of obstacles by means of a radar, and its different applications to the measurement of a liquid in a tank or vessel, or again to the elimination of unwanted or parasitic echos coming notably from the ground, for radars mounted on vehicles or controlling vehicle traffic. To implement the method, the obstacle to be discriminated must have a substantially plane surface. The disclosed method then consists in successively transmitting substantially plane waves at slightly different angular frequencies .omega..sub.i, each wave being furthermore sent with two different polarizations p and p' chosen in such a way that these different coefficients of reflection on the obstacles according to the incidence of the waves give a criterion of discrimination. The processing at reception depends on the use (measurement of distance, elimination of parasitic echos etc.). The main promising feature of the invention lies in the fact that it is possible to make very precise measurements without placing excessive constraints on the transmission pattern of the radar.
