This paper presents a new approach to approximate various complex arithmetic functions for applications in wideband RF transceivers by using stochastic computing based on the piecewise linear (PWL) approximation. The optimized design parameters for PWL approximation are chosen by an optimization algorithm targeting the best tradeoff between hardware complexity and approximation accuracy. Then, this...
In its Carbon Cycle research efforts, prioritized by the National Science Foundation Decadal Survey and mandated by the US Congress, NASA is developing an airborne P-band Ecological Synthetic Aperture Radar called EcoSAR. By using polarimetric and interferometric techniques, and a digital beamforming phased-array architecture, EcoSAR will characterize biomass and ecological structure in three dimensions...
