W artykule przedstawiono miniaturowy radar z syntetyczną aperturą (SAR – ang. Synthetic Aperture Radar) o nazwie „SARENKA”, zaprojektowany przez Zespół Technik Radiolokacyjnych Instytutu Systemów Elektronicznych Politechniki Warszawskiej. Celem prac nad radarem było zaprojektowanie niewielkiego, lekkiego radaru o niskim zużyciu energii, przeznaczonego do montowania na bezpilotowych statkach powietrznych...
In this paper the authors present a concept of flexible system for conducting a wide variety of radar measurements at lower terahertz band (75–500 GHz) along with its laboratory implementation. The presented system comprises four main parts: a motorized measurement table, a modular analogue intermediary block as well as recording and signal generation hardware and software. A design of the commercial-off-the-shelf...
We present in the paper results of a generalised micro-Doppler analysis that is suited to high range resolution radar. The target echo energy is here represented in the three dimensional space of time, Doppler, and additionally range, what can provide more information on target micro-motion than the standard micro-Doppler analysis which is performed in the time-Doppler plane. The analyzed signals...
In this paper a system for radar measurements using a low terahertz frequency band is presented. The architecture of the system is briefly described and some preliminary results obtained with the developed system are attached. A concept to rebuild this system for outdoor radar experiments is presented and the design process described, with an emphasis on the design challenges. Design choices regarding...
Abstract: This paper presents results of DANIEL-35 Synthetic Aperture Radar (SAR) system tests carried out recently by the Warsaw University of Technology (WUT) together with the Air Force Institute of Technology (AFIT), Poland. The DANIEL-35 system is a high resolution (up to 15cm), compact SAR radar operating in the 35GHz band. The system has been developed under the framework of a μSAR project...
