Compressed Sensing experiments in a noise SAR

{0 Comments}

Misiurewicz, J. ; Maslikowski, L. The paper presents a practical application of Compressed Sensing paradigm to a noise synthetic aperture radar. Nonuniform sampling in spatial dimension followed by Compressed Sensing reconstruction of SAR image allows to lower the number of spatial (along-track) domain samples taken in a SAR radar. When the spatial sampling frequency is […]

Integrated sidelobe ratio in noise radar receiver

{0 Comments}

Lukin, K. ; Vyplavin, P. One of the most important characteristics of a radar signal is sidelobes level. It is known that it is possible to build a noise signal generator with power spectrum shape close to Gaussian. Such signal can provide rather low sidelobe level. On the other hand, it is well known that […]

Doppler signal detection using stepped frequency noise radar

{0 Comments}

Lukin, K.; Vyplavin, P. ; Zemlyaniy, O. ; Palamarchuk, V. ; Kim, J.P. ; Cheol Hoo Kim Current paper deals with radar design obtained by combination of two approaches: stepped frequency radar and noise radar for the purposes of SAR imaging. The idea of operation of such combination is following: instead of single frequency signal […]
