Blind calibration of radio astronomical phased arraysStefan Wijnholds
Radio astronomical phased arrays are usually calibrated under the assumption that the observed scene is known. That assumption may not hold if a new frequency window is opened (for example in the case of the currently planned antenna arrays in space observing below 10 MHz) or when there are unexpected source signals such as transients or radio frequency interference (RFI). In this talk, I present recent work on blind calibration of radio astronomical phased assuming that the observed scene is sparse. The resulting method applies sparse reconstruction techniques to the measured array covariance matrices instead of time series data. I discuss the computation speed-up provided by this shift from signal domain to power domain and explain how phase transition diagrams need to be reinterpreted in this contextAdditional information ...

Dutch Ultra Low Power Conference
The medicine of the future you’ll need to take only once, and it’s a bioelectronic one
The Dutch Ultra Low Power Conference brings together Belgian and Dutch professionals and companies involved in the development and application of devices with ultra low power technologies. It targets engineers, designers and technical managers in the advanced field of energy harvesting and ultra low power and energy-efficient designs. The keynote will be given by Wouter Serdijn, professor of bioelectronics at Delft University of Technology.
