Object position fixing method, the range of the object and measuring method of direction and the range of the object and the process which transmits at least

摘要

PROBLEM TO BE SOLVED: To provide a small and highly reliable sensor for accurately discriminating an object by using the smallest data memory.;SOLUTION: The object range/azimuth measuring method is disclosed. At least a part of a first signal is transmitted from a sensor 400. The transmitted signal is reflected from the object, and is received by the sensor 400. At least a part of the first signal is applied to a first mixer 418 and a second mixer 420. The received signal is applied to the first and second mixers. A second signal is generated from the first mixer, and a third signal is generated from the second mixer when the transmitted first signal at least partially overlaps with the reflected signal. An azimuth angle, a dislocation degree from an aim and an object range can be determined from the second signal, the third signal or a combination of these signals. The object range/azimuth measuring sensor is also disclosed.;COPYRIGHT: (C)2004,JPO
