High-speed detection and identification of mobile terminals located in the vicinity highly directive base stations is essential for future mm-wave communication systems. We propose a novel optoelectronic frequency modulated continuous wave (FMCW) radar system detection, localization multiple terminals. The simultaneous achieved by using scanning leaky-wave antennas (LWAs) backscattering communi...

Radar imaging using the synthetic aperture radar (SAR) principle is a common method to obtain information about e.g., surface of target. However, most image formation algorithms for such systems assume (quasi-)static measurements. This may lead errors in processed images if sensor moving during measurement process. especially case frequency-modulated continuous-wave (FMCW)-based sensors since s...

Research on radar-based non-contact vital sign monitoring systems is critical during the COVID-19 epidemic. The accuracy of remote measurements has increased with advancement radar technology and various algorithms. Most studies require subjects to remain stationary, such as standing, sitting in a chair, or lying bed, measurement algorithms have been proposed. However, maintaining stationary st...

With the increase in small unmanned aerial vehicle (UAV) applications several technology areas, detection and UAVs classification have become of interest. To cope with radar cross-sections (RCSs), slow-flying speeds, low flying altitudes, micro-Doppler signature provides some most distinctive information to identify classify targets many systems. In this paper, we introduce an effective model f...

The remote sensing group of the University of Hamburg is working in the field of HF radar since 1980. For the start three CODAR systems have been purchased from NOAA/ERL (developed by D. Barrick’s NOAA group). Based on 16 years of experience a new system called WEllen RAdar (WERA) has been designed at the University of Hamburg in 1996. The new design aims to be as flexible as possible in order ...

Human activity recognition has become an obligatory necessity in day to life and possible solutions can be provided with the technological advancement of sensing field. Radar based its unbeatable unique features been a promising solution for identifying distinguishing human activities recent years. The ascent loss among elderly people care homes during COVID-19 is mainly due poor monitoring ser...

Robust indoor ego-motion estimation has attracted significant interest in the last decades due to fast-growing demand for location-based services environments. Among various solutions, frequency-modulated continuous-wave (FMCW) radar sensors millimeter-wave (MMWave) spectrum are gaining more prominence their intrinsic advantages such as penetration capability and high accuracy. Single-chip low-...
