Abstract

The invention provides a signal processing method and device, equipment and a storage medium. The signal processing method is applied to a vehicle-mounted radar, and comprises the following steps: receiving a target sub-signal which is any one of a plurality of sub-signals included in a radar sub-frame signal; performing sampling processing on the target sub-signals to obtain a plurality of sampling signals; performing distance dimension Fourier processing on the plurality of sampling signals in parallel to obtain a plurality of distance dimension signals; and performing signal fusion processing on the plurality of distance dimension signals to obtain a target distance dimension signal. According to the invention, the distance dimension Fourier processing is carried out on the plurality of sampling signals in parallel, the plurality of distance dimension signals can be obtained at the same time, and the parallel distance dimension Fourier processing consumes less time and is high in processing efficiency. The multiple distance dimension signals are obtained at the same time, so that the multiple distance dimension signals can be subjected to signal fusion processing at the same time, the target distance dimension signal can be obtained through one-time signal fusion processing, and the processing efficiency is high.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a signal processing method, device, equipment and storage medium. Background technique [0002] At this stage, the vehicle-mounted millimeter-wave radar uses a Microcontroller Unit (MCU) for signal processing, and the number of transmission and reception channels supported is limited; for multiple sampling signals received at the same time, it needs to be buffered before further processing. The efficiency is greatly reduced, and the processing time of the radar subframe signal is lengthened. Contents of the invention [0003] In order to solve the technical problems of low processing efficiency and long processing time of radar subframe signals in the prior art, the present invention proposes a signal processing method, device, equipment, and storage medium. The present invention is specifically implemented by the following technical solutions. [0004] This application provide...
