ABSTRACT:
A method and a device for extending the range of radar video data (recurrences) received at the radar pulse repetition frequency (PRF) which can be accented by a digital image converter (DIC) for processing a radar-type image. The frequency of the angular increments (.epsilon.) received for locating the angular position (.theta.) of the radar antenna with respect to a reference direction (north) is modified in order to make the angular increment frequency more nearly a function PRF, thereby guarding against any irregularity of the radar image or any defect of remanence.
