Generation of Airborne Synthetic Aperture Radar Video from Stripmap and Spot mode images and Frame Rate Analysis

VideoSAR is the latest technology, where the radar system enables continuous data collection and processes SAR imagery as a sequence of images continuously when the radar platform either flies by or circles the region of interest. In this paper, the Synthetic Aperture Radar video is generated from Strip map mode and Spot light mode of SAR images. In case of strip map images to video conversion, the continuous image sequence is formed by mosaicing of multiple image strips and or by overlapping of batches. In spot mode, the target of interest is fixed and platform with radar flies by or in circular path and looks at same region of interest. Two to five spot images are considered per second to form the Spot video for 24 frames per second. Interpolation techniques are performed in between the spot images to make it into 24 frames. The results of the airborne Strip map and Spot mode SAR videos are given in the paper. The frame rates also analyzed for the airborne radar of the different velocities, ranges and resolution of images to produce better SAR video.
