摘要 PURPOSE:To improve a distance resolution and to exactly perform an orientation measurement, regarding a radio wave environments measuring device measuring the characteristics, etc., of the propagation route of radio wave in a mobile radio system, etc. CONSTITUTION:The radio wave environments measuring device is provided with a first radio equipment 1 having a transmission and reception part 4 and a measuring part 5, and a second radio equipment having a transmission and reception part 3. The transmission and reception part 3 of this second radio equipment 2 has a constitution transmitting the signal from the transmission and reception part 4 of the radio equipment 1 by turning back the signal. The measuring part 5 of the first radio equipment 1 measures the reciprocated propagation distance of radio wave between the first radio equipment 1 and the second radio equipment 2, the orientation of the second radio equipment 2 and a reception level, etc., based on the signal turned back from the second radio equipment 2.
