This we shall now describe, over several revolutions of the antenna, of the targets slow drowned in the radar clutter with a mobile radar has a rotary antenna

摘要

The present invention relates to a method for detecting targets with a mobile radar to a rotary antenna, in particular the small targets embedded in the radar clutter, without increasing the number of false detections. The method includes a step of determining prédétections during n turns of the antenna, this step includes a step of determining prédétections in turn, each predetection being stored in a grid of cells centered on the position occupied by the radar at the beginning of the current, each cell of the grid, corresponding to a range of azimuth and in a range of distance. This step also includes, at the end of each revolution, a shift of all the prédétections rows in the grid during the preceding turns of the displacement of the radar during the last turn. The method also comprises a step of determination of the detections, a target is detected as soon as a set of prédétections rows in the grid has its distance from the radar which constitute a linear progression during the n turns of the antenna. The application: detection with a radar
