Robust detection in ultra-wideband impulse radar using DPSS-MMSE estimator

Robust detection in ultra-wideband impulse radar using DPSS-MMSE estimator

In this paper, it has been shown that non-stationary received signals at ultra-wideband impulse radars can be addressed by Fourier series model with time-varying coefficients. Next, simply by computing statistical features of the coefficients, we show that this model can be considered as a sum of band-limited sources. Based on the unconditional orthonormal representation of band-limited signals...

Detection of Multiple Targets Using Ultra-wideband Radar

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.),...

Design of an Ultra-Wideband Ground-Penetrating Radar System Using Impulse Radiating Antennas

At TNO-FEL in The Hague, Netherlands, one of the research programs is to explore the use of ultra-wideband (UWB) electromagnetic fields in a bi-static ground-penetrating radar (GPR) system for the detection, location and identification of buried items of unexploded ordnance (e.g. land mines). In the present paper we describe the current status of the development of this system. The UWB ground-p...
