<p>PROBLEM TO BE SOLVED: To make possible result confirmation of speed measurement at high accuracy through an eye and an ear by correcting moving speed based on the crossed axes angle between the advancing direction of a measured object and the projecting direction of measured wave, and outputting it as a sound. SOLUTION: A crossed axes angleθformed out of the advancing direction of a measured object M and the measured wave is previously measured, and the measured crossed axes angle is set by rotating a rotary switch 3. After setting the crossed axes angle, a measurement beginning switch 18 is pushed, and measuring wave fo is projected from an antenna 1 toward the measured object M. Reflecting wave fr from the measured object M is corrected in angle by a speed computing part 4 and output as a correct moving speed. Because this moving speed is displayed by a numeral value on a LED display 6, and output as a sound from a speaker, the moving speed can be confirmed not only by an eye but by an ear.</p> |
