Lv分布是2011年提出的新的视频分布，可以在CFCR域对线性调频信号（LFM）进行参数估计和检测，在高速机动目标检测中也有重要的应用(Lv distribution is a new time frequency distribution, which proposed in 2011. It can estimate and detect the linear frequency modulation signal (LFM) in CFCR domain, and it also has important applications in high-speed maneuvering target detection)
