This project addresses the need for high performance IR LEDs for scene generation in hardware-in-the-loop facilities and for the in situ calibration of IR optics in seekers and reconnaissance satellites. The Ioffe Institute has developed leading technologies to produce LEDs with high output, low operating voltage, and low thermal resistance. These solid-state devices are capable of simulating hi ...

The proposed program is for the development of a fundamental-mode S-band multiple-beam klystron (MBK) circuit and collector compatible with an eighteen-beam electron gun presently under development. The feasibility of the circuit to operate as a broadband high-power amplifying component when used in conjunction with the eighteen-beam gun (41.6 A at 42 kV) has been conclusively establish under the ...

The intent of this project is to improve the radiation hardness of the optical light source and the LiNbO3 integrated optical chip (IOC) to meet the fiber optic gyro (FOG) system objectives for scale factor error (long-term): < 10 ppm and bias drift stability: < 0.001 deg/hr under a total dose: > 300 kRads (Si). This will be accomplished by developing superluminescent LED (SLD) broadband sources ...

Atmospheric disturbances are a major performance-limiting factor in long-range optical systems. In particular, for the Airborne Laser (ABL) the ability of distinguish targets from a long distance is crucial for mission success. Despite the progress in optics and sensor technology, blurring in long-range imaging caused by atmospheric movements and density changes will remain an issue. Digital si ...

Epitaxial Technologies' overall objective is to develop innovative detector technologies that can be used to produce enhanced quantum efficiency and high detectivity VLWIR sensors that can operate at high temperatures. The goal of Phase I will be to investigate dilute nitride strain layer superlattice material structures that are capable of enhanced gain and detectivity and then grow and fabricate ...

We propose a high-frequency (HF) band multiple-input, multiple-output (MIMO) radar with distributed transmitter and receivers. The system will support both Line-of-Sight (LOS) and Over-the-Horizon (OTH) modes. The core of the transceiver is a simple correlation receiver which processes multiple waveforms and generates unified target reports. The transceiver will be implemented on a compact softwar ...

Intelligent Automation, Inc. (IAI) and Arizona State University (ASU) present a systematic approach to stereo image creation, depth estimation, free-viewpoint 3D visualization, and 3D target modeling and visualization. The approach consists of automatic feature point extraction, correspondence and tracking, and stereo image generation from uncalibrated cameras. Additional postprocessing algorithms ...

A recently developed nonlinear controller called theta-D and the Higher Order Sliding Mode (HOSM) control are the centerpiece around which an Integrated Guidance and Control (IGC) scheme and a nonlinear filter technique are built to enhance the lethality of hit-to-kill interceptors and offer a means to increase the maneuver ratio advantage. This proposal includes the development of a 6DOF based I ...

The objective of this research is to develop beta versions of tools for automatically migrating radiation effects predicted in TCAD level tools to compact modeling tools. This transition will enable compact models that possess radiation effects to be quickly generated, which can then be used in circuit design activity. This approach is a substantial improvement over the current ad hoc approaches. ...

Maxion Technologies, in collaboration with a research team at The State University of New York at Stony Brook, will adapt its interband cascade (IC) laser technology to create IR light-emitting-diode (LED) arrays of size 128 x 128 that emit in the 3-5-micron spectral region and meet necessary array performance requirements for IR scene projection. IC-based arrays of LEDs will provide point and ext ...
