Title:
DISTANCE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/029812
Kind Code:
A1
Abstract:
A distance measuring device is comprised of a signal transmitting means (101),
a signal receiving means (102) and a signal processing means (103). The signal
transmitting means transmits a high frequency signal, the components of which
are a plurality of measuring signals in synchronization with an output reference
signal of a reference oscillator (7). The signal receiving means (102) generates
a first local oscillating signal in synchronization with an output reference
signal of a reference oscillator (34), mixes the first local oscillating signal
with a received signal, converts the mixed signal to first intermediate signals
with at least a plurality of different frequencies, mixes the first intermediate
signals corresponding to the measuring signals with a plurality of second local
oscillating signals with at least different frequencies in synchronization
with or orthogonal to an output signal of a second mixer (35), and converts the
mixed signal to a plurality of second intermediate signals. The signal processing
means (103) detects a phase difference of the second intermediate signals and
measures the distance between the signal transmitting means (101) and the signal
receiving means (102) with high accuracy
