Technology progresses in microelectronics promote on-board imaging of soaceborne SAR

摘要

The realization of spaceborne SAR imaging on-board is a necessary trend for digital avionics in speedily advancing SAR remote sensors. Powerful and efficient application-specific instruction-set processors (ASIPs) play a leading role in this solution to keep data processing system functioning real-time. A few improving methodologies, technologies and advanced EDA tools in microelectronics make it possible to design such a SAR imaging processor easier and faster. Some evident and important delegates of them, including system-level modeling and simulation for SAR imaging algorithm, available IP library designed by experts, ideas of designing domain-specific SoC with multiple processors and the microelectronic ways to ruggedize avionics applied in space radiation-active environment, are presented heuristically in this paper.
