<P>PROBLEM TO BE SOLVED: To provide an angle measurement device estimating incident angles of incoming signals by angle measurement processing of one time, even if the scale of an arithmetic unit is small and wideband signals are observed. <P>SOLUTION: In the angle measurement device including: a plurality of sensors for observing signals; means for performing statistical processing of time series data obtained from the observations by the sensors; and means for measuring the incident angles of the signals by using a statistical processing result of the statistical processing, the means for performing the statistical processing includes: means for converting the time series data obtained by the observation in each of the sensors into frequency data; means for dividing the frequency data into blocks of a plurality of frequency bands; and means for performing interpolation processing on the frequency data for every divided block with respect to the positions of the sensors. <P>COPYRIGHT: (C)2012,JPO&INPIT |
