<P>PROBLEM TO BE SOLVED: To obtain a communication apparatus and a radar device, capable of correcting a phase of a light signal transmitting on a light transmission path without preparing change-over switches for short circuit in each system even in the case a transmission phase of a light transmission line is fluctuated. <P>SOLUTION: The communication apparatus and the radar device are provided with: a reference signal generation section 16 for generating a plurality of light reference signals; a plurality of reference signal output sections 12a, 12b for respectively output such reflection signals that the light reference signals are reflected by signal reflection sections 13a, 13b and returned; a plurality of photo-electric conversion means 24a, 24b for converting each reflection signal output from the reference signal output sections 12a, 12b to each electric signal; phase comparison means 25 for obtaining a phase difference between the electric signals converted by the plurality of photo-electric conversion means; and delay control means 26 for controlling a delay of signals to be transmitted through a plurality of light transmission lines 9a, 9b by the phase difference obtained in the phase comparison means 25. <P>COPYRIGHT: (C)2013,JPO&INPIT |
