Principles of biological echolocation applied to radar sensing: applying biomimetic sensors to achieve autonomous navigation Universiteit Antwerpen
This article introduces the application of principles from biological echolocation to radar sensing. A novel biomimetic radar sensor is presented whose features are based on the relevant morphology of a bat. Signal properties accessible to bats as well as biologically feasible processing techniques are discussed, and we show how they translate to the domain of pulseecho radar. We demonstrate that by applying these techniques, our radar system ...
Radar networks : a review of features and challenges Universiteit Gent
Networks of multiple radars are typically used for improving the coverage and tracking accuracy. Recently, such networks have facilitated deployment of commercial radars for civilian applications such as healthcare, gesture recognition, home security, and autonomous automobiles. They exploit advanced signal processing techniques together with efficient data fusion methods in order to yield high performance of event detection and tracking. This ...
Simulation and Detection Performance Evaluation of a UAV-mounted Passive Radar KU Leuven
© 2018 IEEE. This paper presents the concept of an UAV-mounted passive radar. Since the radar has no active transmitter and uses signals transmitted by illuminators of opportunity (IOO), it is a low cost, lightweight, low-power consuming solution perfectly fitting for mobile applications, especially for mounting on a UAV. Moreover, it does not require supplemental frequency allocation and creates no additional interference to existing wireless ...
Embedded DSP-based Telehealth Radar System for Remote In-door Fall Detection KU Leuven
Telehealth systems and applications are extensively investigated nowadays to enhance the quality-of-care and, in particular, to detect emergency situations and to monitor the well-being of elderly people, allowing them to stay at home independently as long as possible. In this paper, an embedded telehealth system for continuous, automatic, and remote monitoring of real-time fall emergencies is presented and discussed. The system, consisting of a ...
bioRad: biological analysis and visualization of weather radar data Instituut voor Natuur- en Bosonderzoek
Weather surveillance radars are increasingly used for monitoring the movements and abundances of animals in the airspace. However, analysis of weather radar data remains a specialised task that can be technically challenging. Major hurdles are the difficulty of accessing and visualising radar data on a software platform familiar to ecologists and biologists, processing the low-level data into products that are biologically meaningful, and ...
On the application of an optimized frequency-phase modulated waveform for enhanced infrared thermal wave radar imaging of composites Universiteit Gent
Thermal Wave Radar (TWR) imaging employs the concept of pulse compression in order to obtain an increased probing depth and depth resolution in infrared thermographic testing of materials. The efficiency of the TWR imaging is highly dependent on the nature of the employed excitation signal. Most studies exploit the use of an excitation signal with an analogue frequency modulation (e.g. sweep signal) or a discrete phase modulation (e.g. Barker ...
Mapping of agricultural subsurface drainage systems using a frequency-domain ground penetrating radar and evaluating its performance using a single-frequency multi-receiver electromagnetic induction instrument Universiteit Gent
Subsurface drainage systems are commonly used to remove surplus water from the soil profile of a poorly drained farmland. Traditional methods for drainage mapping involve the use of tile probes and trenching equipment that are time-consuming, labor-intensive, and invasive, thereby entailing an inherent risk of damaging the drainpipes. Effective and efficient methods are needed in order to map the buried drain lines: (1) to comprehend the ...
A biomimetic radar system for autonomous navigation Universiteit Antwerpen
This paper presents a novel biomimetic radar sensor for autonomous navigation. To accomplish this, we have drawn inspiration from the sensory mechanisms present in an echolocating mammal, the common big-eared bat (Micronycteris microtis). We demonstrate the correspondence in both the hardware, system model, and signal processing. To validate the performance of the sensor, we have developed a complementary control system based on subsumption ...
