摘要
采用Radon-Wigner变换方法,实现了噪声背景下单分量线性调频信号和多分量线性调频信号的检测。仿真结果表明,对于线性调频信号检测,Radon-Wigner变换方法性能明显优于Wigner-Ville分布法。
In this paper, by using Radon-Wigner transform, the detection of single component and multi-component linear frequency modulation（LFM） signals under noise background is realized. The simulation results demonstrate that the detection performance of LFM signals which by using Radon-Wigner transform has better than the detection performance which by using Wigner-Ville distribution.
