CEI is currently funded for development of a Direct Band Pass Under sampling (DBPU) design of 900 MHz (approximately) center RF using an ADC clock of 1000 MHz. The RF bandwidth is approximately +/- 50 MHz (i.e. the same as the current SPS-49 radar). This yields an aliased spectrum centered around 100 MHz which is then easily digitally down converted via a digital LO following the ADC. It therefore ...

In the Phase II effort, CEI will develop an Advanced Direct Digital Exciter for Radar (ADDER) targeted for the AN/SPS 49A(V) (SPS-49) search radar as part of the SPS-49 technical refresh with relevance to other military and commercial applications (e.g. exciter, Software Defined Radio (SDR)). ADDER will directly replace the multi-step Intermediate Frequency (IF) analog conversion with direct-digit ...

EXPLORATORY DEVELOPMENT OF AN ADVANCED, DIRECT AIR SAMPLING GAS CHROMATOGRAPHY (GC) MODULE IS PROPOSED. THE GC RIODULE CAN BE READILY COMBINED WITH EXISTING ION MOBILITY SPECTROMETRY (INS) EQUIPMENT FOR DETECTING AND MONITORING CHEMICAL WARFARE AGENTS, E.G., THE CAM (CHEMICAL AGENT MONITOR) CURRENTLY ADOPTED BY SEVERAL NATO MEMBER STATES. THE GC MODULE INCORPORATES A NOVEL, AMBIENT AIR SAMPLING DE ...

High power lasers are needed for many airborne applications. These lasers must be compact, reliable in high vibration environments, and must also have a low per unit cost. Aculight proposes to develop a high repetition rate laser with average power of 10-20 watts using novel packaging designs and manufacturing methods. When fully developed, this technology will provide flight-worthy lasers at a ...

"Diode pumped solid state lasers are starting to be used in many military vehicles, including, missiles, unmanned aerial vehicles (UAV), and aircraft platforms. The military applications include laser radar systems, laser designators, and opticalcountermeasures. All of these systems require high power, very efficient, rugged, and low cost laser diodes to pump the solid state lasers.While laser d ...
