Acoustic Detection and Tracking of Small, Low-flying Threat Aircraft
نویسنده
چکیده
Acoustic sensor arrays can be used effectively to provide situational awareness and perimeter defense against small low-flying threat aircraft. Being small and flying low, these aircraft can elude radar detection. However, similar to heavy ground vehicles, these small aircraft emit strong harmonic lines that can be detected and tracked (bearing) at long range. Experimental results from a 16-element cross array are presented for several types of a small aircraft.

Solar Energy System Design of Ultralight Aircraft for Smoke Detection and Fire Alarm Proposes
Abstract: The purpose of this paper is to design and evaluate the construction of a lightweight solar aircraft that is capable of flying continuously for 24 hours relying solely on solar energy. The required energy is absorbed during the day by solar panels, some is used directly for flight, and the excess energy is stored in the aircraft battery for overnight flight. The aircraft will then be ...
متن کاملMulti-Modal Netted Sensor Fence for Homeland Security
Potential terrorists/adversaries can exploit a wide range of airborne threats against civilian and military targets. Currently there is no effective, low-cost solution to robustly and reliably detect and identify low observable airborne vehicles such as small, low-flying aircraft or cruise missiles that might be carrying chemical, biological or even nuclear weapons in realistic environments. Th...

In recent years, developments in unmanned aerial vehicles, lightweight on-board computers, and low-cost thermal imaging sensors offer a new opportunity for wildlife monitoring. In contrast with traditional methods now surveying endangered species to obtain population and location has become more cost-effective and least time-consuming. In this paper, a low-cost UAV-based remote sensing platform...
متن کاملCentralized Path Planning for Multi-aircraft in the Presence of Static and Moving Obstacles
This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...
متن کاملDetecting, Tracking, and Identifying Airborne Threats with Netted Sensor Fence
Today’s technological advances allow for the development of unmanned aerial systems, fixed-wing aircraft, that are small enough and fly low enough to elude conventional radar detection. Such aircraft could carry out chemical, biological, or nuclear attacks, or they could be employed to smuggle drugs or illegal immigrants across the border. This chapter describes a low cost, low power (potential...
