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: Upon each new detection, called pivot detection, by a radar system, the method includes the steps consisting of: grouping together, with the pivot detection, grouped detections, defined as detections that belong to a sweep preceding the sweep of the pivot detection and that have a non-nil probability according to a grouping criterion; filtering the grouped detections so as to keep only detections that are kinematically strictly coherent with the pivot detection, by: initializing a histogram, each dimension of which is a temporal variation of a coordinate measured by the radar system; computing a potential value interval for each coordinate of the pivot detection and each grouped detection; computing a minimum temporal variation and a maximum temporal variation for the or each coordinate from potential value intervals of the pivot detection and each grouped detection; incrementing the set of classes of the histogram whose index along each dimension is located between the computed minimum and maximum temporal variations; and detecting a target once at least one class of the histogram reaches a predefined value.

Abstract: The invention relates to a system and a method for automatically harmonizing the position and/or orientation between an apparatus on board a mobile carrier and a reference frame of said mobile carrier, said mobile carrier being provided with an inertial unit able to provide measurements in the reference frame. The system comprises:
at least one accelerometer mechanically coupled to the onboard apparatus, and providing acceleration measurements in a reference frame referred to as the associated onboard apparatus,
a reception unit configured to receive measurements provided by said inertial unit and measurements provided by the accelerometer,
a computing unit configured to calculate values of parameters defining a geometric transformation for conversion of data from the reference frame of the carrier and the reference frame of the onboard apparatus, from the measurements, carried out for at least two different flight orientations, by said inertial unit and by said accelerometer.-

Abstract: A method for determining wave height by means of a radar carried by an aircraft, the method implementing the following steps: a first step of pointing the antenna of the radar; a second step of determining the clutter acquisition plan according to the altitude of the aircraft; a third step of determining, for each clutter zone defined by the acquisition plan, two Doppler parameters PARA1 and PARA2 characterising the zone as a whole; a fourth step of calculating the average values of the parameters PARA1 and PARA2 over all of the zones in question; and a fifth step of estimating the wave height from the averages of the parameters PARA1 and PARA2. The wave height estimated in this way is transmitted to the aircraft and used to determine the conditions for the water landing of the aircraft.

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 wave transmitted by an antenna made up of an array of radiating elements, two pulse waves are transmitted, each modulated by a phase shift law known as modulation phase shift, the phase shifts being in opposition, a first wave being transmitted by a sub-array of radiating elements referred to as odd and the second wave being transmitted by a second sub-array of radiating elements referred to as even, the two sub-arrays being interleaved, the transmitted wave being the combination of the first wave and the second wave.

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.
