PURPOSE:To enable to clearly discriminate the distinction between the case of absence of target and the case of the stoppage of a radar, by adding a radar sweep indicating function. CONSTITUTION:A position information for one sweep, which is converted from a polar coordinate to an orthogonal coordinate in a memory writing address control part 2, is, in addition to a memory 4, sent to a sweep forming memory, mounted at a sweep forming part 19. In case the sweep forming memory is read, memory is read in turn in synchronism with horizontal and vertical signals of TV, and a radar sweep is indicated on a picture. |
