Otten, M.P.G. (author), van Rossum, W.L. (author), van der Graaf, M.W. (author), Vlothuizen, W.J. (author), Tan, R.G. (author)An X-band Digital Array Synthetic Aperture Radar for a Short Range Tactical UAV is presented. The Frequency Modulated Continuous Wave radar principle in combination with digital beam forming over 24 receive channels is used to achieve low power and advanced imaging SAR capabilities on small platform. Novel SAR imaging modes are discussed, and...conference paper 2014

Belfiori, F. (author), Anitori, L. (author), van Rossum, W.L. (author), Otten, M.P.G. (author), Hoogeboom, P. (author)The paper presents different processing schemes that have been investigated in order to evaluate the direction of arrival (DOA) with a multiple-input multiple-output (MIMO) radar. Conventional digital beam forming (DBF) and super resolution algorithm (MUSIC) have been applied. The results provided by them have been compared with a compressive...conference paper 2011

Belfiori, F. (author), van Rossum, W.L. (author), Peter Hoogeboom, P. (author)Multiple-input-multiple-output (MIMO) processing is a consolidated technique in communication systems thanks to the benefits that it offers in multipath fading environments. In recent years, studies have shown how the performances of conventional phased-array radar can be improved by using the same approach. This letter illustrates how the...article 2011
