Current monostatic radar systems suffer fine tracking and discrimination performance degradation when encountering mainlobe jammers deployed within a reentry complex. As a result our forces may be vulnerable to attack. During Phase I, we have developed di

This proposal will address the development of a digital receiver and exciter (DREX) technology for next-generation scalable missile-defense radar. A DREX is currently being specified at the sub-array level to feed an analog tile or panel subarray. This al

This work develops Distributed Information Assurance (DIA) system based on the distributed data mining technology. The key capabilities are: ++Multi-agent architecture linking multiple, heterogeneous network-sensors to perform distributed and decentralized analysis of the data, supporting local management of the policy-based control for different sensors. ++Collection of distributed data mining a ...

Two-phase loops have significant flight heritage having demonstrated high reliability and long life in the space environment. However, a shortfall of existing aerospace-grade two-phase loops is their relatively low heat flux capacity in the range of tens of watts/cm2. This program applies a new evaporator design to cooling of laser diode arrays on space platforms. The new evaporator design will ...

Nowadays missile threats, specifically coordinated attacks involving multiple missiles, have become increasingly challenging. It is hard to fast and effectively allocate the rich and varied U.S. defense capabilities to negate the aforementioned missile threats. There is a need for an integrated system for battle managers, fire control and operators to effectively manage the U.S. missile defense ca ...

Detection, tracking, and identification of dim targets are challenging for the following reasons. First, MDA radars encounter strong clutter due to chaff and decoys. The manmade clutter can be non-Gaussian, non-stationary, and unpredictable. Second, the distance between radar and a target can be hundreds of miles, which make the radar returns very weak. Third, some target motions may be maneuverin ...

The design and development of scalable panel-based phased-array radars requires the high density integration of solid-state components and adequate thermal mitigation within the array lattice constraints. The current integration technologies such as system-on-a-chip (SOC), multi-chip-module-deposition (MCM-D), and system-on-package (SOP), will help miniaturizing sub-modules for various functional ...

Missile threats faced by our country are constantly increasing in lethality. The weapon used to counter such missiles is the kinetic interceptor. To work effectively, the reentry vehicle (RV) location must be precisely known. Confusing objects within the reentry complex make the key discrimination process very difficult. Coherent distributed aperture (CDA) radar represents an important advance in ...

The objective of the proposed research and development work is to create new types of compact, autonomous explosive-driven high-power microwave (HPM) systems based on the magnetic flux compression generator (FCG). There will be no moving parts (to include armatures) in these devices; the systems will be completely solid-state units. They will include all components necessary for operation: a comp ...

This proposal will address the development of a wideband digital receiver and exciter (DREX) technology for next-generation scalable missile-defense radar. A DREX is currently being specified at the sub-array level to feed an analog tile or panel subarray in order to generate flexible waveforms and beams with improved performance. The technical challenge is to meet the required receiver sensitivit ...
