<P>PROBLEM TO BE SOLVED: To provide a radio wave environment measurement device capable of measuring a delay time and a power level of each delay wave constituting a multipath, and detecting an arrival direction of each delay wave. <P>SOLUTION: A radio wave environment measurement device has: a receiving part receiving and demodulating a broadcast wave to output a demodulation signal; a delay profile generator generating a delay profile for the received broadcast wave based on the demodulation signal; a GPS receiver performing positioning based on a GPS signal; a storage device storing the delay profile and a positioning result at a position where the broadcast wave giving the delay profile is received with associating with each other; a radio wave tower position information acquiring part acquiring positional information of a radio wave tower that transmits the broadcast wave; and an analyzing part analyzing an arrival direction of a multipath component included in the broadcast wave based on a set of delay profiles and positioning results acquired for at least three points, and the positional information of the radio wave tower to output an analysis result. <P>COPYRIGHT: (C)2012,JPO&INPIT |
