Embodiment 1

[0060] Such as figure 1 As shown, a radar parallel processing system includes:

[0061] A signal generating module, configured to generate echo data of N columns of antennas, the signal generating module adopts a two-stage parallel mode;

[0062] For the signal generation module, if the serial design is adopted, its running time will increase significantly when the number of channels and the number of simulation targets increase, thereby reducing the overall operating efficiency. Therefore, this system adopts a two-stage parallel mode for processing the signal generation module. Its specific process is as image 3 Shown:

[0063] Assuming that the system has n targets, k threads can be set to process each target of the first module in parallel. The threads adopt the first-come-first-served mode for the targets, and at the same time, the first module and the second module perform signal synchronization. When All the targets of the first module generate corresponding echo sig...

Description

technical field [0001] The invention relates to the technical field of signal parallel processing, in particular to a radar parallel processing system and method, a storage medium, and a terminal. Background technique [0002] The radar signal processing system has the characteristics of high floating-point calculation density, high parallelism, and algorithm concentration. The existing mainstream parallel processing schemes generally use embedded platforms such as DSP+FPGA. Processing flow, DSP completes the data processing flow of target detection, quantity estimation, target track tracking, etc. There are also some mainstream processing solutions that use GPUs for parallel processing. This solution generally uses the CUDA library of the GPU to complete parallel signal processing and data processing in the GPU. [0003] In the existing DSP+FPGA embedded parallel processing platform, the main frequency range of its mainstream processors generally ranges from 100MHZ to 1GHZ...
