Abstract

In order to satisfy the requirement of image registration in multi-band SAR system, a controlling unit with real time phase difference detection was implemented using in this paper. The phase difference detection was based on the DFT method combined with undersampling technique. This paper also provides a comprehensive architecture of the time service recoding and embedded subsystem in the controlling unit. Both ADC consistency and phase difference detection performance test were conducted in the experiment to ensure less than 10ps phase difference resolution requirement.
