Title:
ANGLE MEASURING DEVICE, ANGLE MEASURING METHOD, AND VEHICLE-MOUNTED DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/157924
Kind Code:
A1
Abstract:
An angle measuring device (1) is configured to be provided with: a signal extracting unit (31) which extracts, as a first demodulated signal, a signal including a first reflected wave (20-1) and not including a second reflected wave (20-2), from among received signals (22-n) output from one or more reception antennas (21-n) among a plurality of reception antennas (21-1) to (21-N), and which extracts, as a second demodulated signal, a signal including the second reflected wave (20-2) and not including the first reflected wave (20-1); an angle of elevation calculating unit (32) which calculates a target angle of elevation by performing monopulse angle measurement employing a sum signal of the first demodulated signal and the second demodulated signal, and a difference signal of the first demodulated signal and the second demodulated signal; and an azimuth angle calculating unit (5) which calculates a target azimuth angle using received signals (22-1) to (22-N) output from the plurality of reception antennas (21-1) to (21-N).
