The SARENKA SAR system - Experimental results of ISAR imaging

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 size unmanned aerial vehicles (UAV). For these purposes the SARENKA SAR system using the Frequency Modulation Continuous Wave (FMCW) concept was designed and tested. The first field tests of the system were done using a cooperative ship on a lake as a target. As a result Inverse SAR (ISAR) images of the target were obtained. In this paper the preliminary results of this experiment are presented and discussed.
