80GHz class low power 1D level sensor for high dust environment capable of observing inside enclosed structures

摘要

The present invention relates to a 1D radar sensor, and more particularly, to a 1D radar sensor capable of three-dimensionally measuring a level of a raw material such as powder in a silo. Disclosed herein is a 1D radar sensor. 1D radar sensor according to an embodiment of the present invention includes a transceiver that transmits a radar and receives a reflected radar, a rotation control unit that changes the position of the transceiver so that the radar transmission angle of the transceiver is changed, and a radar from which the transceiver is emitted Upon receiving, an operation signal for controlling the rotation control unit is transmitted to the rotation control unit to set the position of the transceiver, and the reception time of the radar received by the transceiver fixed at a specific position is calculated to be between the transceiver and the raw material. and a control unit operable to continuously measure the level of the raw material by performing a control operation for calculating the distance of the predetermined number of times.
