<p><P>PROBLEM TO BE SOLVED: To provide a radar device capable of keeping a synchronous relation between an excited wave and a modulated wave even when fluctuation of the excited wave is changed, and outputting a sufficient transmission wave. <P>SOLUTION: This radar device for transmitting the transmission wave in each transmission period repeated periodically is equipped with a master timing control circuit. The master timing control circuit operates an elapsed time between a reference timing and the excited wave relative to the n-th (n is a positive integer) transmission period, and adjusts a generation timing of an excited trigger signal corresponding to an elapsed time in the n-th transmission period so that the excited wave and the modulated wave keep mutually-overlapped prescribed synchronous relations relative to the (n+1)-th transmission period. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
