摘要：
Clutter computation becomes a bottleneck of radar simulation. To solve this problem, a parallel simulation method for clutter computation is introduced based on GPU platform. Blocks in GPU compute the clutter of each scattering unit in parallel, and threads in each block parallel compute the clutter of each differential unit in scattering unit. Combined with the RTX real-time operating system, the system based on RTX and CUDA cooperative work is designed, which had been applied in hardware-in-the-loop simulation. The experimental result shows that the introduced method achieves a significant speedup of clutter computation in a relevant missile test of hardware-in-the-loop simulation, while ensuring the accuracy of the calculation.
