Ultra Wideband Radar Cross Section Reduction by using non-Resonant Unit Cells

Monopole Antenna Radar Cross Section Reduction with Plasma Helix

In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...

Ultra-Wideband Automotive Radar

A lot of progress has been made for automotive radar during the last years. There are two types of automotive radar; “long-range radar at 77GHz with a range capability up to 200m“ for automatic cruise control (ACC) and “short-range radar at 24/26 and 79GHz up to 30m“ for anti-collision. Long radar with narrow radiation beam enables a automobile to maintain a cruising distance, while short-range...

Augmented Reality Using Ultra-Wideband Radar Imagery

The U.S. Army Research Laboratory (ARL) has been investigating the utility of ultra-wideband (UWB) synthetic aperture radar (SAR) technology for detecting concealed targets in various applications. We have designed and built a vehicle-based, low-frequency UWB SAR radar for proof-of-concept demonstration in detecting obstacles for autonomous navigation, detecting concealed targets (mines, etc.),...

Radar Sensing Using Ultra Wideband – Design and Implementation

Ultra-wideband (UWB) has received significant attention for applications in target positioning and wireless communications recently. The extremely short pulses in turn generate a very wide bandwidth and offer several advantages, such as large throughput, covertness, robustness to jamming, lower power, and coexistence with current radio services. UWB not only can transmit a huge amount of data o...
