、第２図は表示映像図である。[Claims for Utility Model Registration] Echo information obtained by emitting measurement pulses from a radar detection unit at regular intervals is temporarily stored in a buffer memory using distance pulses generated each time the detection unit moves a predetermined distance. A control circuit (hereinafter referred to as a temporary storage control circuit) for guiding the temporarily stored echo information to a main memory for obtaining a display image with the X axis as the travel distance and the Y axis as the distance to the target; an echo display having a display control circuit for writing and reading out the temporarily stored echo information so that the oldest echo information of the displayed image is erased and moved according to the moving distance, comprising: a. The echo information from immediately after to the next distance pulse is processed to display S.
the temporary storage control circuit provided with a circuit for improving the /N ratio; b. for integrating the distance pulses and displaying the distance traveled from the reference point in numbers on the X-axis at the edge of the display image; A device comprising: a numerical circuit; The brief description of the drawing has been amended as follows. The simple explanatory section of the drawings in the specification, "...shows an example of an image." is amended as follows. The drawings show an embodiment, and FIG. 1 is a block configuration diagram, and FIG. 2 is a display image diagram.
