Embodiment Construction

[0081] Some terms used in this application are explained below to facilitate the understanding of those skilled in the art. It should be noted that when the solution of the embodiment of the application is applied to the 5G system, or the existing system, or other systems that may appear in the future, the name of the device may change, but this does not affect the implementation of the solution of the embodiment of the application. implement.

[0082] 1) Synthetic aperture radar is a high-resolution imaging radar. By actively emitting microwaves, it can detect in various complex environments and generate high-resolution radar images similar to optical photography. The synthetic aperture radar has the advantages of small size, light weight, There are many advantages of high imaging accuracy and less susceptibility to environmental influences. For an explanation of the synthetic aperture radar, reference may be made to the elaboration of the prior art.

Abstract

The embodiment of the invention discloses an imaging method and device, a radar system, electronic equipment and a storage medium. The method comprises the steps of obtaining at least two groups of original radar data from different radars, carrying out image registration and time domain coherence superposition, and obtaining a first target image, wherein each group of original radar data respectively corresponds to one radar, the original radar data from different radars comprise different radar information, and after image registration and time domain coherence superposition are carried out on the original radar data, the obtained first target image has higher physical resolution, so that the resolution of the generated radar image is improved, the image information in the radar image is enriched, and the positioning accuracy and the driving safety of the vehicle are further improved. The scheme can be further used for improving the capability of an automatic driving or advanced driving assistance system (ADAS) and can be applied to the Internet of Vehicles, such as vehicle external connection V2X, inter-vehicle communication long term evolution technology LTE-V and vehicle-vehicle V2V.

Description

technical field [0001] The present application relates to the technical field of automotive fusion perception, and in particular to an imaging method, device, radar system, electronic equipment and storage medium. Background technique [0002] With the development of society, smart terminals such as smart transportation equipment, smart home equipment, and robots are gradually entering people's daily lives. Sensors play a very important role in smart terminals. Various sensors installed on the smart terminal, such as millimeter-wave radar, lidar, camera, ultrasonic radar, etc., sense the surrounding environment during the movement of the smart terminal, collect data, and identify and track moving objects. And the recognition of static scenes such as lane lines and signs, and combined with navigator and map data for path planning. Sensors can detect possible dangers in advance and assist or even take necessary avoidance measures autonomously, effectively increasing the safe...
