Title: Distance measuring device
Inventor: YOSHIKAWA SHIRO
IPC: G01S13/28
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To solve a problem that it takes a long time conventionally to obtain a measured value since a distance measured value is not obtained until transmission tones of a plurality of frequencies are sequentially received and an ambiguity removing sequence of all the transmission tones are completed. SOLUTION: A delay time calculator 34 calculates a delay time from an average phase inputted by an average phase detector 12 when performing measurement of high accuracy, and eliminates ambiguity generated at that time by a delay time calculated value with not high accuracy obtained from a phase gradient to a frequency direction obtained by a phase gradient detector 32. A distance value can be obtained from the delay time and a known velocity of light. This distance measuring device disuses a transmitting signal switching sequence by using a same distance measurement signal for phase difference measurement and ambiguity elimination. Therefore, a parallel processing of the phase difference measurement and the ambiguity elimination is possible, and distance measurement can be performed in a shorter time as compared with a conventional device.
