METHOD FOR DETECTION BY LONG INTEGRATION AND CORRESPONDING RADAR SYSTEM

METHOD FOR DETECTION BY LONG INTEGRATION AND CORRESPONDING RADAR 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 (110) a histogram (H), each dimension of which is a temporal variation of a coordinate measured by the radar system; computing (120, 130) a potential value interval for each coordinate of the pivot detection and each grouped detection; computing (140) 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 (150) the set of classes of the histogram whose index along each dimension is located between the computed minimum and maximum temporal variations; and detecting (160) a target once at least one class of the histogram reaches a predefined value.
