摘要： A method comprises at least: a first radar processing for locating and estimating the trajectory of a target on the basis of measurements of radial distances, of Doppler frequency and of angle of azimuth and of elevation of the target arising from a radar signal emitted towards the target; a second radar processing of location and of trajectory of the target along a vertical axis, by applying the principle of the inverse synthetic antenna; the disparity between the given trajectory and the trajectory estimated by the first processing, projected on a horizontal plane, and the disparity between the given trajectory and the trajectory estimated by the second processing according to the vertical axis being used to control the direction of displacement of the target.

摘要： A detection method implementing an FMCW waveform is provided, the emitted waveform is formed of a recurring pattern of given period Tr covering an emission frequency band of given width B, each pattern being divided into a given number P of sub-patterns of duration Tr/P covering an excursion frequency band ΔF=B/P, the sub-patterns being mutually spaced by a frequency interval equal to ΔF. The radar performs: a first distance-compression processing operation carrying out a low-resolution distance compression at the scale of each recurring pattern on a fraction B/P of the emission band of width B corresponding to the frequency band covered by each of the sub-patterns; a Doppler processing operation on a given number N of successive recurrences so as to form P ambiguous distance-Doppler maps of low distance resolution, the maps being segmented into various speed domains; a second distance-compression processing operation of resolution that differs depending on the speed domain to which the relative speed of the target with respect to the radar belongs.

摘要： A radar attached laterally to airplane fuselage to detect obstacles on a collision course with a portion of the airplane facing the radar, comprises an emission antennal channel and reception antennal channels in the same plane, the form of the wave and field of angular coverage of the radar depending on the velocity of the airplane, the processing means comprising the steps: Establishing in the radar coordinate system a first distance/Doppler map allowing echoes to be separated into distance and Doppler resolution cells in a reception antennal channels; Establishing a second distance/Doppler map of smaller size by selecting a subset of distance/Doppler resolution cells corresponding to the possible positions of targets liable to collide with the wing of the airplane; Establishing new distance/Doppler maps by forming beams computationally from the subsets of distance resolution cells retained for each reception antennal channel; and Temporal integration, in each beam, of successive distance/Doppler maps.

摘要： A digital receiver comprising at least two reception pathways, the method carries out a digital inter-correlation of the signals obtained as output from at least two filters of different central frequencies and different ranks, the rank and the central frequency of the filters being chosen as a function of a determined frequency-wise search domain. For a determined search domain, the various sampling frequencies of the reception pathways are chosen so that the ambiguous frequencies resulting from the spectral aliasings vary as a monotonic function of the true frequency of the signals.
