<p>PURPOSE:To accurately detect a location of a target stably, by averaging the data of the distances and directions of receiving signals. CONSTITUTION:The data of reflected waves are memorized to a memory circuit 3 every minute angle and distance. A signal completion detecting circuit 6 detects the completion of reflected wave signals, and transmits signal completion signals to a quantization direction detecting circuit 7 and a quantization distance detecting circuit 8. The quantization direction detecting circuit 7 detects the central directions of reflected waves at each distance, and delivers the data of each central direction to a direction averaging circuit 9. The direction averaging circuit 9 obtains mean about these central direction groups, and sends the data of a target direction of a target to a terminal 9a. The quantization distance detecting circuit 8 transmits the data of each central distance to a distance averaging circuit 10. The distance averaging circuit 10 gains the mean of the central distance, and conveys the data of the target distance of the target to a terminal 10a.</p> |
