This report presents a tutorial description of MIT Lincoln Laboratorys Infrared Airborne Radar (IRAR) sensor suite. IRAR, which was flown aboard a Gulfstream G-1 aircraft, was used to collect multispectral ground-images using the following sensors: active (laser radar )

High-resolution angle estimation for an automotive FMCW radar sensor
free download

This paper introduces the application of high-resolution angle estimation algorithms for a 77GHz automotive long range radar sensor . Highresolution direction of arrival (DOA) estimation is important for future safety systems. Using FMCW principle, major challenges One of the great mysteries of the brain is cognitive control. How can the interactions between millions of neurons result in behavior that is coordinated and appears willful and voluntary There is consensus that it depends on the prefrontal cortex (PFC). Many PFC areas receive

CC Attribution 3.0 License Impact of system parameter selection on radar sensor performance H.-L. Bl echer M. Andres C. Fischer A. Sailer M The interferences coming from the radar members degrade the detection and recognition performance of the radar sensor networks (RSNs) if the waveforms of the radar members are nonorthogonal. In this paper, we analyze the interferences by exploring the polarization Ultra wideband radar sensor networks have intensive military and commercial applications. However, how to mitigate the interference to the existing systems and increase the spectrum utilization for UWB radar sensor networks should also be studied carefully. While energy
