摘要： 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.

摘要： The present invention relates to a method for determining detection thresholds of a CFAR detection system of a sensor observing an environment, the CFAR detection system being provided with an estimator adapted to determine an estimate of parameters related to noise affecting the sensor depending on parameters related to the environment, the method comprising the steps of:
estimation of parameters related to noises, in order to obtain a parameter vector,
computation of first detection thresholds so that, for all possible configurations of the parameter vector, the CFAR detection system operates at a predefined false alarm probability,
characterization of estimation errors of the estimator, and
correction of each first detection threshold in order to obtain second detection thresholds, the step of correcting taking into account the error parameters.-

摘要： The invention relates to a target characterisation method for a detection device of multi-panel radar or sonar type with electronic scanning, comprising the steps of:
generating a plurality of pulses on a plurality of antenna panels (PE1, PE2, PE3) of the detection device according to a temporal and angular interleaving pattern, so as to perform a scan over all of the relative bearing domain of the detection device;
generating a plurality of detection maps, by the acquisition of a plurality of observations combined with one another by coherent or non-coherent integration of the echoes corresponding to the plurality of pulses, each detection map being obtained in a given direction (EL1, EL2, EL3) corresponding to the width of the main lobe of the antenna panel;
combining the detection maps so as to detect a presence of a target in the relative bearing domain of the detection device.-

摘要： 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.

摘要： 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.

摘要： A detection system includes a phased array antenna having unitary radiating elements, the system being suitable for, in each cycle, successively directing, by way of the successive application of a first and a second determined phase law to the electrical signals for supplying power to the array antenna, the antenna radiation towards a first target area (Z1), then a second target area (Z2), which is separate from the first target area (Z1), and determining an image of each target area (Z1) on the basis of the echoes received from each of the first and second target areas.

摘要： A method comprises at least the following steps: a step of acquiring data by radar to obtain an SAR image covering a given geographical domain; a step of acquiring at least one secondary image covering the domain, produced by a source external to the radar, the image supplying information on the colors of the constituent elements of the SAR image; a step of superimposing the SAR image and the secondary image; a step of assigning colors to the elements on the basis of their position in the superimposed secondary image.
