A low-cost fiber-based octave-spanning frequency comb system operating in the mid-IR region is proposed, which is based on femtosecond-Tm-fiber-laser-pumped supercontinuum generation in a mid-IR-transmitting dispersion-engineered fiber. An all-fiber femtosecond mode-locked Tm-doped fiber laser at 2 micron will be used as a seed source for mid-IR supercontinuum generation. A femtosecond soliton fib ...

An approach to make a long endurance UAV with an 18 hour endurance and large payload will be developed based on an existing, fielded capability present operationally deployed.  The system will be built from COTS equipment minimizing cost and allowing for rapid maintenance and upgrading of the system as technology develops.  The system will be fully autonomous through launch, mission flight and r ...

Rather than continuing to approach cyber security problems in a reactive fashion, ASD proposes to move to a proactive posture; anticipating and eliminating vulnerabilities while also being prepared to effectively and rapidly defend against attacks. Our approach collects data about the attacker as well as the attack, which it processes in real time. The data (observations) is then used by our prote ...

During the normal course of research, development, and testing by the DOD small quantities of environmentally hazardous waste propellants, explosives, and pyrotechnics (PEP) are produced.  The compliance costs and burden associated with open burn/open detonation operations are considerable, including permit fees, ground water, soil and air sampling, analysis and monitoring of environmental impact ...

A TEO-PHASE INVESTIGATION OF TECHNIQUES FOR IMPROVING THE CONFIDENCE LEVEL OF EMITTER DETECTION AND IDENTIFICATION IN ELECTRONIC WARFARE SYSTEMS IS PROPOSED. PHASE I WILL CONCENTRATE ON THE DEVELOPMENT OF LOW LEVEL IMAGE PROCESSING TECHNIQUES APPLIED TO HISTOGRAMMED RADAR WARNING RECEIVER PULSE DATA IN ORDER TO LOCATE OBVIOUS EMITTERS AND AREAS OF PROBABLE AMBIGUITY. PHASE II WILL APPLY EXPERT SYS ...

OF SPECIFIC INTEREST TO THE U.S. AIR FORCE IS THE SIMULATION OF FEW VERSUS FEW AIR-TO-AIR ENGAGEMENTS TO EVALUATE NEW DESIGNS FOR WEAPON SYSTEMS, AERODYNAMICS AND TACTICS. A DIGITAL MODEL WITH THIS CAPABILITY WOULD HAVE TO SATISFY THE REQUIREMENTS OF THE INDIVIDUAL AIR FORCE APPLICATIONS, INCLUDING CONFORMITY TO ESTABLISHED AND PROPOSED MULTIPLE MODEL SIMULATION FRAMEWORKS. THE TWO MOST STRONGLY S ...

AN INCREASINGLY IMPORTANT REQUIREMENT IN ECM JAMMER SYSTEMS IS COHERENT RECEPTION OF THREAT SIGNALS, PRECISE MANIPULATION OF THE WAVEFORM AND RETRANSMISSION BACK TO THE THREAT FOR PURPOSES OF DECEPTION. THE DRFM (DIGITAL RF MEMORY) IS ONE PARTICULAR TYPE OF STORAGE DEVICE WHICH MAKESCOHERENT JAMMING MODULATION SCHEMES POSSIBLE. DRFM DEVICES,HOWEVER, ARE EXPENSIVE AND HAVE SEVERAL PERFORMANCE PROBL ...

Precision time bases capable to withstanding high shock application have been difficult to achieve due to the inherent sensitivity of stable, frequency control component to vibration and inertial loading. These limitations are due substantially to packaging requirements of the components, e.g. hermetic, non-surface-contracting enclosures. The assembled component and its package could not be rigi ...

To address the need of the Air Force in terrestrial based optical imaging for space situational awareness (SSA) with high-resolution imagery, Applied Science Innovations, Inc. (ASI) proposes development of the Coded-Aperture Lucky Imaging for Space Situational Awareness (CALISSA) – a novel, computational coherent-imaging technique capable of high-resolution and high performance imaging without i ...
