Abstract: A detection method for a given mission comprises at least: one phase of analysing the environment using a waveform chosen beforehand, the signals acquired with this waveform being analysed by processing means in order to deduce therefrom environmental characteristics; and one phase of generating an optimal detection wave depending on the environmental characteristics and characteristics of the mission.

Abstract: Disclosed is a method and a system for the automated computation of a length or width dimension of a moving platform. The method includes sending radio waves toward the platform along a predetermined transmission axis and acquiring at least one digital power profile signal representative of a received reflected signal power as a function of a radial distance along the transmission axis relative to a reference point. This method next includes applying a filtering operator on the acquired digital power profile signal, making it possible to obtain a filtered digital signal, determining, by computation, a first radial distance corresponding to a first variation peak of the filtered digital signal and a second radial distance corresponding to a second variation peak of the filtered digital signal, and the computing a radial dimension of the platform as a function of the first and second radial distances.

Abstract: The method, implemented within a mission system that comprises an electro-optical camera which generates video images, detects movable/moving objects, and tracks a target object; and a radar sensor which generates signals and detects blips, consists of: acquiring a video image provided by the camera and blips provided by the radar sensor at the time instant of generation of the acquired video image; converting the geographic position of each acquired blip, expressed in a first reference frame associated with the radar sensor, into a geographic position expressed in a second reference frame associated with a camera pointing direction of the electro-optical camera at the time instant of generation of the video image; and correcting the geographic position of each blip in the second reference frame, according to the characteristic features of the camera, in a manner such as to obtain a position in the image.

Abstract: A detection method for a given mission comprises: a phase of analysing the environment, wherein phase elements of influence on the sea clutter perceived by the radar are sought and stored in memory; a phase of updating the path to be followed by the carrier depending on the requirements of the mission and the elements of influence issued from the result of the analysing phase, the path to be followed decreasing the power of the clutter received by the radar when the antenna is pointing towards a search zone liable to contain a target; the phases being repeated throughout the mission.

Abstract: This swarm (101) is made up of a plurality of drones (111-115), the drones being flying drones, the drones forming a communication network with one another. It is characterized in that the swarm implements, autonomously, an obstacle avoidance functionality (20) based on a collaborative observation of the environment of the swarm by each of the drones and the sharing of obstacle detection information among the drones.

Abstract: A radar imaging device having a mission to produce a radar image of a given target, comprising a step of determining the trajectory of the carrier of the imaging device comprises at least: a phase of determining a segment of trajectory for the picture capture, as a function of the position of the target and of the type of image to be produced, the picture capture segment being dedicated to the picture capture of the target by the imaging device; a phase of adding a segment of trajectory of stabilizing the carrier, situated upstream in the extension of the picture capture segment; a phase of addition of a segment of trajectory for homing the carrier onto the stabilizing segment.
