Frequency modulated continuous wave (FMCW) radar systems suffer from permanent leakage due to their continuous operation. Especially in integrated circuits this leads to the well known issue of on-chip leakage due to limited isolation between transmit and receive circuitry. In addition, we investigate short-range (SR) leakage resulting from signal reflections of an unwanted close object located...

Frequency Modulated Continuous Wave (FMCW) radars have been used by snow scientists for the past 30 years. This radar technology provides a promising alternative to point measurements, as properties such as snow depth can be measured quickly and nondestructively. Recent advances in microwave FMCWradar technology have resulted in lightweight, portable instrumentation. This is in contrast to the ...

This paper describes the design and development of a ground based Frequency Modulated Continuous Wave (FMCW) radar system in Multimedia Univeristy (MMU), Malaysia. In this project, a ground-based fully polarometric, C-band, high bandwidth linear FM-CW and real time imaging radar system is to be designed and constructed. The system should have the capability to measure the complex scattering mat...

Ground-based frequency-modulated continuous wave (FMCW) radar measurements made throughout the 2002–03 NASA Cold Lands Processes (CLPX) mission in Colorado, USA, were designed to study the major electromagnetic transitions within the alpine snowpack over a wide range of conditions, and their effect on measurements made with different active radar measurement parameters. Measurements during 2002...

In this paper, we present a novel signal processing method for video synthetic aperture radar (ViSAR) systems, which are suitable for operation in unmanned aerial vehicle (UAV) environments. The technique improves aspects of the system’s performance, such as the frame rate and image size of the synthetic aperture radar (SAR) video. The new ViSAR system is based on a frequency-modulated continuo...

based on the compressed sensing theory, if a signal is sparse in a suitable space, by using the optimization methods, signal could be accurately reconstructed from measurements that are significantly less than the theoretical shannon requirements. the sparse representation may exist for the signal and it is not available for the noise; this could be used to distinguish these two. on the other h...
