This paper presents the design and implementation of a C-band Analog-Front-End (AFE) for Frequency Modulated Continuous Wave (FMCW) Radar. This AFE is based on commercial off-the-shelf (COTS) radio frequency components. The system was designed to be used in various radar applications, including short range mode, Synthetic Aperture Radar (SAR) and Inverse Synthetic Aperture Radar (ISAR). The AFE system...
W artykule przedstawiono projekt miniaturowego radaru z syntetyczną aperturą (SAR – ang. Synthetic Aperture Radar) o nazwie SARENKA dedykowanego dla bezzałogowych statków powietrznych (BSP). Głównym celem pracy było opracowanie nisko budżetowego radaru SAR charakteryzującego się zarówno małymi wymiarami jak również małą wagą. SARENKA jest radarem FMCW (ang. Frequency Modulation Continuous Wave) pasma...
This paper presents the system design, signal processing aspects and measurement results of an experimental Synthetic Aperture Radar (SAR) named SARENKA. The presented system is a C-band radar developed recently at the Warsaw University of Technology. The main goal of this work was to develop a low-cost, small-size and low-weight radar with high resolution dedicated for small aircrafts and medium...
The paper presents a concept of using universal software radio peripheral (USRP) as a hardware platform for frequency modulation continuous wave (FMCW) synthetic aperture radar (SAR). The concept presented has been successfully verified through several measurements in the laboratory, as well as in real scenarios where the USRP-based SAR radar was mounted on a ground moving platform and SAR images...
