<p><P>PROBLEM TO BE SOLVED: To specify a radio wave emission source transmitting a pulse compression radio wave having a frequency wide band over reception band ranges of a plurality of receivers without using a receiver having a wide-band reception band range. <P>SOLUTION: A sampling clock common to at least two receiving devices is supplied, to thereby control synchronization of each receiving device, and frequency data in a pulse of a pulse compression signal detected respectively by each receiving device are rearranged in the order of newness of each sampling time, to thereby generate one piece of synthetic pulse data. A lower limit frequency, an upper limit frequency, and a change with time of the frequency of one piece of synthetic pulse data are detected, and the pulse compression radio wave having the frequency band over the reception band range of each receiving device is detected. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
