<P>PROBLEM TO BE SOLVED: To obtain a space communication device having high discriminability even when positions of two or more targets mutually get near, and also having the responsiveness to a modulation signal of a pulse train etc. <P>SOLUTION: The space communication device includes: an interrogator (10) that has a radio wave signal transmission section (12), a scanner (13), a scanner control section (14), a light receiving section (17), and a signal processing section (18); and one or more responders (20) that have a radio wave signal receiving section (21), a responder information generating section (23), a modulating signal generator (24), and a light source (25). The light receiving section is composed of a light receiving element of a single element, the scanner control section controls the scanner to scan a receiving field of view two-dimensionally and transmits angular information on the scanner, and the signal processing section identifies the responder based on individual information included in a signal after demodulation and specifies the direction of the identified responder based on the angular information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
