Abstract

The invention discloses a vehicle-mounted radar imaging method and device, and electronic equipment. Wherein, the method includes: intercepting the vehicle radar echo data; dividing the vehicle radar echo data into near-end full aperture data and far-end aperture data based on the echo data demarcation point; Imaging processing, obtaining a far-end image, and performing imaging processing on the near-end full-aperture data by using a second imaging algorithm to obtain a near-end image; splicing the near-end image and the far-end image to obtain a target scene image. The invention solves the technical problem that in the related art, the vehicle-mounted radar can only use the far-end imaging or the near-end imaging, and cannot complete the near-distal joint imaging processing, which reduces the image processing efficiency.

Description

technical field [0001] The present invention relates to the technical field of vehicle radar, in particular, to a vehicle radar imaging method and device, and electronic equipment. Background technique [0002] In related technologies, vehicle-mounted SAR is a new mode of automotive radar at present. Through two-dimensional imaging processing of radar echoes, images that can reflect the two-dimensional geometric configuration of characteristic targets are obtained. [0003] At present, common SAR is characterized by narrow beam width in azimuth, long action distance and long synthetic aperture length. When performing imaging processing with a fixed azimuth width, all azimuth apertures are sub-apertures or full apertures, and only full-aperture imaging algorithms or sub-aperture imaging algorithms are used to complete two-dimensional imaging processing. The vehicle-mounted SAR is obviously different from the ordinary SAR. It is characterized by a wider beam width in azimuth,...
