Abstract: Three-axis stabilized platform, as a key motion compensation technology for airborne Synthetic Aperture Radar (SAR), is used to isolate attitude variations and mechanical vibration from aircraft, resulting in stable antenna pointing. In this paper design of based-TMS320LF2407 DSP digital controller for airborne SAR antenna three-axis stabilized platform is presented. The requirement of airborne SAR to stabilized platform and the advantages of this DSP used to implement motion controller are described. The theoretic block and mathematic model of the control system as well as the structure of DSP digital controller are given.
Keywords: Airborne SAR, Stabilized platform, TMS320LF2407 DSP, Digital controller
