Adversaries reverse engineer weapons systems to replicate a system's advanced capabilities or discover its weaknesses. Many of these critical systems are real-time systems. The restrictions of real-time have a significant impact on the implementation of anti-tamper technology. This work will build on our prototype for transforming source code and machine code to add state-of-the-art protection a ...

Radar targets provide a rich scattering environment that produces from 5 to 25 dB target fluctuations. The spatial dependence of target scattering has been understood for some time and it has been shown that targets produce essentially independent scattering returns when radiated from sufficiently different directions. Thus, if receivers are distributed over a wide enough area, which is the premis ...

Ballistic Missile Defense System (BMDS) maintenance costs are high, making up as much as 60-70% of the total system life-cycle cost. Moreover, inefficient maintenance policies and procedures can have adverse national security ramifications. We propose a Global visibility and Central Command approach to meet the maintenance and inventory management challenges. The proposed system consists of thre ...

C2BMC is an important component of BMDS. The logistics support tail sustainment challenges in C2BMC are related to the unusual spiral development process employed by C2BMC. Formal metrics such as MTTR and MLDT have not been defined. Nor have spare parts analysis, training needs analysis or documentation support issues been formalized. There is enormous scope for both process re-engineering and tec ...

One of the most dangerous cybersecurity threats is ``control hijacking'' attacks, which hijack the control of a victim application, and execute damaging system calls by assuming the identity of the victim process's effective user. These types of attacks are highly hazardous because commercial applications with such vulnerabilities appear to be wide spread, as shown in the rampancy of recent worms ...

The goal of this SBIR project is the development of a fiber-coupled diagnostic system for the comprehensive Tx/Rx-mode calibration and performance-monitoring of large-scale phased antenna arrays. In the proposed calibration system, innovative electro-optic (EO) field sensors will monitor near-field amplitude and phase emanating from the array under observation during Tx-mode calibration, while com ...

The primary objective of CU Aerospace's Phase I work will be to investigate innovative iodine injection concepts for the chemical oxygen-iodine laser (COIL) that improve mixing at higher total pressures. The designs will be made to significantly improve the pressure recovery of COIL systems while retaining efficiency. The results of the Phase I research will lay the foundation for developing a h ...

Accurately acquiring, tracking, discriminating and engaging a missile/warhead amongst closely spaced decoys immersed in clutter is a challenge for one or more radar systems. The objective of this proposal is to optimally design multi-sensor data collection, processing and fusion strategies when multiple radars and/or other sensors are employed to form a single integrated picture of the battlespace ...

Many advanced HgCdTe (MCT) infrared detector structures are grown by the molecular beam epitaxy (MBE) technique, which is especially sensitive to small imperfections, impurities, precipitates, and polishing damage on the substrate surface. In order to achieve very high crystalline quality MCT structures, the substrate surface must be of superior quality (MBE-quality). EPIR demonstrated the ability ...

The MDA's request to detect, track and discriminate long range targets requires infrared focal plane arrays (IRFPAs) that have higher sensitivities, longer cutoff wavelengths (>14 µm), larger formats (> 256 x 256), and higher operating temperatures than the current infrared technology. PbSnTe is an ideal material for the MDA's requirements. Its carrier mobilities and quantum efficiencies are comp ...
