Direct conversion of DC energy to RF energy via switched systems such as Class D, E, and F amplifiers is limited by the switches currently available. Presently available switches are voltage limited, resistive transition time limited, and rate of current rise limited. Furthermore, high power switched amplifiers are limited by the thermal dissipation of the switches which are required to open and c ...

Next-generation infrared (IR) seekers will have an aerodynamically-engineered nose cone geometry with a significantly higher degree of curvature compared to conventional hemispherical domes. To prevent unwanted specular + diffuse reflections that obscure the IR focal plane array, the interior of the dome should ideally be treated with an anti-reflective (AR) layer that suppresses stray light refle ...

This program will study and demonstrate novel air guiding fibers to address critical optical power handling limitations of current optical fibers. The innovative antiresonant hollow core fiber designs proposed here, have the potential for high power light transport over long fiber lengths with orders of magnitude higher damage and nonlinear thresholds compared to solid core fibers. In particular, ...

The challenge of ascertaining technical requirements and pertinent information embedded in Test Program Sets (TPSs) and determination of Test System (TS) capabilities that can perform those requirements is an area of interest that holds promise for improving various aspects of weapons system acquisition, repair and maintenance lifecycle costs. One example is when test systems as a whole or tester ...

RDRTec proposes to design, develop, and demonstrate feasibility and benefit of adding automatic threat and friendly radar waveform detection techniques to the Common RAdar Collision Avoidance System (C-RACAS). C-RACAS is designated the AN/ZPY-9 and is a part of the future Triton Integrated Functional Capability (IFC) 5 configuration. The C-RACAS has three C-Band Active Element Scanned Array (AESA) ...

In response to the Navy SBIR Topic N19-014, IRGLARE is pleased to propose the development of 4.5µm Quantum Cascade Lasers delivering continuous wave optical power significantly exceeding 10W in a nearly Gaussian output beam (M2 < 1.5). The very high power level will be achieved by scaling device dimensions both laterally and along the growth direction, while still preserving operation on fundamen ...

TransWave Photonics, LLC in collaboration with the University of Texas at Austin proposes to demonstrate a new active region configuration for the mid-wave infrared quantum cascade lasers that provide a possibility of scaling the brightness of the device emission by at least a factor of 5 over the current state-of-the art. The proposed laser design concept is based on coherently coupling of the li ...

For this research program, Mainstream will collaborate with Colorado State University (CSU) to develop a nanostructured heater capable of curing aerospace grade composites out-of-autoclave (OOA). The use of autoclaves is the primary cost driver in composite manufacturing due to size limitations, long processing times, and inefficient energy usage. Therefore, the Navy is looking to develop a nanost ...

CURRENT BEST TELEMETRY SOURCE COMBINER SYSTEMS USED AT WEAPONS TEST RANGES ARE CAPABLE OF SELECTING THE "BEST" SIGNAL FROM SEVERAL REDUNDANT SOURCES. HIGHER DATA RATES AND DETERIORATION OF TEST RANGE SNRS HAVE PRECIPITATED A REQUIREMENT FOR AN AUTOMATED TELEMETRY SIGNAL PROCESSING SYSTEM CAPABLE OF COMBINING AVAILABLE SOURCES INTO AN ENHANCED "BEST SIGNAL."
