IPC: G01S13/34
Filed: 2020-06-30
Abstract: A radar detection method and a related apparatus are provided. The method includes: intercepting a plurality of measurement units MUs from a beat frequency signal of a radar based on a time domain sliding step (S1101), where a time domain length of each of the plurality of MUs is greater than a time domain length of a preset sliding step; determining frequency information of each MLT (S1102); and obtaining a radar point cloud detection result based on the frequency information of each MU (S1103), where the detection result includes at least one of a speed of a target object or a distance of the target object. This method can improve a point output rate (that is, point cloud density) of a radar and avoid signal-to-noise ratio loss without increasing costs significantly.

IPC: G02B5/18
Filed: 2020-07-10
Abstract: A diffractive optical device includes at least one diffractive optical element. The diffractive optical element generates light having a first order and light having a second order from a laser beam input to the diffractive optical element, and superimposes the light having the first order and the light having the second order on each other on an optical axis of the laser beam to cause interference between the light having the first order and the light having the second order, the light having the first order and the light having the second order having diffraction orders different from each other. The diffractive optical element includes a first phase pattern and a second phase pattern. The first phase pattern converts the laser beam into a line beam. The second phase pattern diffracts the laser beam in a short axis direction of the line beam to generate the light having the first order and the light having the second order. A first focal plane of the light having the first order is located at a position different from a second focal plane of the light having the second order on the optical axis of the laser beam.
