<p>PURPOSE:To read the same storage contents to plural radars at the same time by converting each position in an antenna direction into virtual X-Y coordinates and generating an address, and storing the coordinates in X-Y memory and also reading and storing them a buffer circuit temporarily, radar by radar. CONSTITUTION:When an address switch circuit 6 is connected to a terminal 0, the storage contents of a memory element corresponding to a position which is specific range ahead of an antenna in its direction are erased. Then the time when a direction line crosses corresponding area of the memory element farthest from a radar is made longer than the switch period to erase the storage contents in said rotation completely. Further, when the address switch circuit 6 is connected to a terminal 1, the storage contents of the memory element corresponding to each position in the direction are sent to an input arithmetic circuit 4 and compared with a video signal from an input buffer circuit 3 at every equal range to write a signal having larger amplitude in a memory element. Thus, the stored signal is swept and correlated (n) times in the switch period, so the S/N ratio is improved and the signal has no loss.</p> |
