Design of Radar Imaging Processing Platform Based on the Architecture with Digital Signal Acquisition Board and GPU

In response to the need for larger calculations and higher real-time performance in the radar imaging processing process, it is proposed a radar imaging processing platform architecture, which is consisted of a high-speed digital signal acquisition board, a fiber-PCIE board, and a GPU server structure. The radar signal after A/D is sent from the high-speed digital signal acquisition board to the fiber-PCIE board through the optical fiber, which uses the aurora 64b/66b optical communication protocol to achieve a 10Gbps transmission rate. Then the digital signal is transmitted to the CPU through the PCIE port. After that, it is transported to the GPU memory for subsequent imaging processing. The design is simulated and verified, the test results of the acquisition board are given, and The Omega-K Algorithm (ωKA) is taken as an example to give the GPU processing results.
