Summary:PURPOSE:To enable an off-center display with the title equipment without increasing the capacity of a main memory by controlling the data quantities transferred from a buffer memory to the main memory at every angle in accordance with the off-set position data against the displaying center and searching azimuth data. CONSTITUTION:This element writes radar signals from an input terminal 11 in a buffer memory 13 after A/D conversion 12 and further writes the digital signal in a main memory 14 after performing orthogonal transformation on coordinates. In addition, the equipment is provided with a transferring quantity controlling section 31 to which offset data and the azimuth data of an angle counter 23 are inputted and the quantity of the data transferred from the buffer memory 13 to the main memory 14 is controlled at every angle. Therefore, the capacity of the main memory 14 can be minimized to the extent required for display.
