Title: Fm-cw radar device and distance/speed detection method for moving object
Inventor: OKUTSU KAZUHIKO
IPC: G01S13/34
Filed: 2006-09-29
Abstract: <P>PROBLEM TO BE SOLVED: To perform distance and speed detection suitable for a low-speed moving object such as a walker by a method not requiring symmetry as in a case where a triangular wave is used for modulation in an FM-CW radar.  <P>SOLUTION: A radar wave, which is FM-modulated with a control signal coming from a VCO 12 and changing like a sawtooth, is transmitted from an antenna 19. A reflected wave from the moving object, which is a target, is received and combined with a transmitted wave in a mixer 23, and a Doppler frequency is detected from a mixer output. Since the distance to the target is a function of the Doppler frequency, the distance can be found according to this functional relation. By catching a moving target at two time points leaving a prescribed period therebetween, its speed can be found from the distance between two points.  <P>COPYRIGHT: (C)2008,JPO&INPIT
