The analysis of UWB SAR system error

Focusing on the design of Ultra WideBand (UWB) Synthetic Aperture Radar (SAR) adopting deramping technology, the paper has studied the sources of the system error and the error tolerable levels. The system error classification is introduced according to the error's characteristics. The effect of each kind of error on UWB SAR system is presented. The paper has allocated the error budget with a UWB SAR system which has about 200 Mhz bandwidth and works at UHF/VHF band.
