Study on extracting target information from the high-low resolution two-dimensional images on stepped frequency signal

In the process of stepped frequency radar signal, we usually obtain the range information of the target through the target extraction algorithm. For the moving target, in order to avoid the issues such as amplitude loss, target lost and fake peak, we need to do the speed compensation before extracting target directly. Based on the target range high-low-resolution two-dimensional image analysis and processing, this paper gives a method to extract the target range and speed information at the same time from the two-dimensional images, and the constraints of the method for stepped frequency signal parameters design.
