VideoSAR is a land imaging mode. By using VideoSAR, the radar data can be persistently collected on a target of interest,and then "movie-like" images can be created for an extended period of time. We derive the relation expression between frame rate limited by resolution and radar center frequency, and the VideoSAR images can be formed from both the non-overlapping and overlapping sub-apertures. This work provides a useful theoretic approach for designing the VideoSAR system. The theoretical results are validated through stationary target and moving target simulations at the frame rate of 37.50 fps.
Key words： synthetic aperture radar (SAR); VideoSAR; frame rate; stripmap
