- Abstract:
- In area of metrology there is often a necessity of microwave distance meter calibration. The calibration is executed by distance measuring from the microwave distance meter to conductive plane, of which distance is defined accurately (by means of micro-steps of step motor, which moves the plane or by means of the reference laser distance meter). Some disadvantages may appear at higher distances when accuracy of the measurement are affected by parasitic reflections of microwave radiation from walls of the room, in which calibration is executed. For example, if a flaring angle of the microwave distance meter is 23°, then the first reflection from the sidewall, at 1.5 m distance, occurs at 7 m and from the framework, at 1 m distance, at 4 m yet. Such a situation significantly affects execution of calibration at the distances more than 4 m. There is several manners how to solve such a problem.
