This paper provides a comprehensive review of the vision-based See and Avoid problem for
unmanned aircraft. The unique problem environment and associated constraints are …

A real-time vision system with multiple cameras was developed for UAV collision warning
and visual navigation for fixed-wing small-or medium-sized aircrafts. The embedded vision …

This article mainly focuses on the vision-based obstacle avoidance of unmanned aerial
vehicle (UAV). Detecting the obstacle and controlling the UAV to avoid it are two key …

A photonic approach to concurrently measure the angle-of-arrival (AOA) and the chirp rate of
a linear frequency modulated (LFM) signal is proposed and experimentally demonstrated …

A five-camera vision system was developed for UAV visual attitude calculation and collision
warning. The vision system acquires images by using five miniature cameras, stores, and …

The importance of vision-based systems for Sense-and-Avoid is increasing nowadays as
remotely piloted and autonomous UAVs become part of the non-segregated airspace. The …

Passive positioning systems with a small aperture array exhibit poor accuracy of target
estimation in far-field environments. To improve this accuracy, this paper presents a novel …

Abstract Unmanned Aerial Systems (UASs) have recently become a versatile platform for
many civilian applications including inspection, surveillance and map**. Sense-and-Avoid …

Passive positioning systems with a small aperture array exhibit poor accuracy of target
estimation under strong interference in near-field environments. To improve this accuracy …
