Progress in spaceflight research has led to the introduction of various manned and
unmanned reusable space vehicle concepts, opening up uncharted opportunities for the …

In this study, we discuss recent advances and state-of-the-art sense-and-avoid solutions for
small unmanned aircraft systems. The purpose of this paper is to equip the reader with the …

Wireless sensing has demonstrated the potential of using Wi-Fi signals to track people and
objects, even behind walls. Yet, prior work in this space aims to merely detect the presence …

There have been a number of successful attempts in designing obstacle avoiding robots.
These works differ by selection of sensors, path mapping process and the algorithms …

The growing adoption of unmanned aerial vehicles (UAVs) for tasks such as eCommerce,
aerial surveillance, and environmental monitoring introduces the need for new safety …

We have developed a multitone modulated continuous wave (MTCW) Lidar system made of
a CW laser with multiple fixed RF tones for a high precision range finding and velocimetry. In …

This article develops a novel physics-inspired traffic coordination approach and applies it to
unmanned aircraft system (UAS) traffic management. We extend available physics-inspired …

This paper presents an energy-optimal guidance and control strategy for 4-dimensional (4D)
Trajectory-Based Operations (TBO) in the descent phase, supporting the development of 4D …

This paper focuses on one of the collision avoidance scenarios for unmanned aerial
vehicles (UAVs), where the UAV needs to avoid collision with the enemy UAV during its …

Demand for 3D planning and guidance algorithms is increasing due, in part, to the increase
in unmanned vehicle-based applications. Traditionally, two-dimensional (2D) trajectory …
