The Multi-Chromatic Analysis uses interferometric pairs of SAR images processed at range sub-bands and explores the phase trend of each pixel as a function of the different central carrier frequencies to perform absolute topographic measurements. The previous work on the subject has started demonstrating the practical feasibility of the technique by using a set of SAR data collected by the airborne...
This paper investigates an universal algorithm and hardware architecture for context-based statistical lossless compression of multiple types of data using FPGA (field programmable gate array) devices which support partial and dynamic reconfiguration. The proposed system enables optimal modeling strategies for each source type whilst entropy coding of the modeling output is performed using a statically...
The new generation of Remote Sensing instruments usually generates a huge amount of data, which have to be transmitted down to a ground station for processing. In order to reduce the bit rate before the data is transmitted to the ground station, data compression is usually used. Developing ASICs for the data compression can save power and weight, and can increase the level of integration. Data compression...
