The solid state semiconductor technology in radar systems supporting the U. S. Army's ballistic missile defense program increases its vulnerability to the effects of high power, fast rise-time EMP, HPM, and UWB pulses. Recent research has shown that using carbon nanotubes (CNTs) can greatly improve the performance of a limiter. Improvements upon a previous X-band waveguide plasma limiter can be m ...

The mitigation of mainlobe jamming is essential to missile defense radar performance. Applied Radar is currently investigating distributed aperture and adaptive processing architectures that promise a new generation of advanced radar performance. Our proposed program will research the application of these distributed aperture radar techniques to determine the mainlobe jammer suppression possible w ...

The design and development of phased-array radars requires the integration of solid-state components and adequate thermal mitigation within the array lattice constraints. The current trend is towards increasingly planar designs and a reduction in the array depth. The MDA SPEAR program is one example in which a planar T/R “tile” architecture is utilized. System-on-a-chip technologies such as Si ...

The objective of this project is to develop a novel expander that can increase the efficiency of cryocoolers for IR sensors at very low temperatures and in remote cooling and across gimbal applications. Miniature Thermoacoustic Expanders (MTAE) that employ high energy acoustic waves generated with no moving parts at the cold expander to produce efficient cooling over a wide range of temperatures a ...

Plasma Sciences Corporation (PSC) will build upon previous and ongoing research in transient voltage phenomena to develop a microwave front end limiter that can withstand high power RF interference with minimal impact on normal operations. Participating in the effort is Professor Popovic of Old Dominion University (ODU), a subject matter expert, who will support plasma computer modeling, simulati ...

Dynamic Structures and Materials, LLC (DSM) proposes the development of a compact, proportional piezoelectric motor actuation technology with miniature electronics, optimized actuator hardware and integrated position feedback capability. The new actuation system will be optimized and characterized in an integration test bed representative of system loads (physical, thermal, vibration) relevant to ...
