摘要
针对CW脉冲和线性调频(LFM)信号,利用Radon变换沿直线积分的特性,将其与时频分布(TFD)结合在一起,抑制多频率分量信号各个分量之间的交叉项干扰,提高时频分布的时频二维分辨力。通过仿真数据验证算法具有良好的时频分辨能力以及抑制交叉项干扰能力。
Aim at CW pulse and linear frequency modulated （LFM） signal, Radon transform and time-frequency distribution （TFD） were conjoined together for Radon can be integral along the line. It can control the cross terms among the multi-component signal and increase the resolution of time-frequency. The simulation data were used to improve the high time-frequency resolution and great control cross terms capability of the TFD based on Radon transforms.
