摘要
Aiming at the real-time synthesis requirements of wideband, high-speed, and parallel signals in the antenna array synthesis system, an antenna array time delay compensation method based on GPU is proposed. Firstly, the feasibility of typical integer time delay compensation methods on graphic processing unit (GPU) platform is analyzed, and an integer time delay compensation method based on data block overlap retention is designed. Secondly, the advantages and disadvantages of typical fractional time delay compensation methods are compared, and a frequency-domain fractional time delay compensation method suitable for GPU parallel acceleration is designed. Finally, the experimental verification of the antenna array time delay compensation method based on GPU is carried out. The experimental test results show that on the basis of ensuring the correctness of the time delay compensation, the time delay compensation method based on GPU is about 18 times faster than the traditional serial CPU time delay compensation method on the acceleration rate. The time delay compensation method based on GPU can realize the multi-antenna signal real-time synthesis. © 2023 Chinese Institute of Electronics. All rights reserved.
