Abstract Circular Trace Scanning Synthetic Aperture Radar (CTS-SAR) is a new operation mode radar, which can be used for wide observation. CTS-SAR have the characteristic of high time-space resolution, short repetition visit period and wide observation area. It can observe wide area in a short time with great efficiency for slow platform specially. The moving model and range model of CTS-SAR are advanced, and the Doppler characteristic and azimuth resolution characteristic of CTS-SAR are analyzed base on the above models. Then the imaging method of CTS-SAR is discussed. The computer simulation results validate the analyzed conclusions and the imaging method. CTS-SAR is competent for wide observation.
