Automatic target detection and localization using ultra-wideband radar

Self-Training Algorithms for Ultra-wideband Radar Target Detection

An ultra-wideband (UWB) synthetic aperture radar (SAR) simulation technique that employs physical and statistical models is developed and presented. This joint physics/statistics based technique generates images that have many of the “blob-like” and “spiky” clutter characteristics of UWB radar data in forested regions while avoiding the intensive computations required for the implementation of ...

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.),...

Through-the-Wall Localization of a Moving Target by Two Independent Ultra Wideband (UWB) Radar Systems

In the case of through-the-wall localization of moving targets by ultra wideband (UWB) radars, there are applications in which handheld sensors equipped only with one transmitting and two receiving antennas are applied. Sometimes, the radar using such a small antenna array is not able to localize the target with the required accuracy. With a view to improve through-the-wall target localization,...
