Document Type and Number:
WIPO Patent Application WO/2019/119227
Kind Code:
A1
Abstract:
Disclosed are a position detection method and device, a rotary radar system, and an unmanned aerial vehicle. The position detection method is applied to a rotary radar. The position detection method comprises: S101: calibrating the initial position of the rotary radar; S103: recording, based on the initial position, pulse signals output by a detection device; and S105: determining the current position of the rotary radar according to the number of the pulse signals. Designed in the present invention are a position detection method and device capable of accurately detecting the rotary position of the rotary radar, a rotary radar system, and an unmanned aerial vehicle. The current position of the radar system can be determined according to the initial position of the rotary radar in combination with the number of pulse signals output by the detection device, so that the position of the rotary radar can be detected accurately and stably without interference from external factors.
