The primary function of missile defense radars is to detect and intercept incoming missiles. As the technology for missile systems is advanced, the next generation of missiles will have added capabilities to deploy countermeasures and masking techniques to foil radar detection. The next generation of radars therefore, must also have added capabilities to counter those advanced threats. One crucial ...

Hittite proposes to develop an advanced wideband high-speed, low-power, radiation-tolerant ADC for embedded applications such as miniature receiver/exciter modules (mDReX) and wafer-scale arrays (WSAs). Offering higher speed and lower power than competing devices, the ADC will advance the state of the art and enable next-generation digital sub-arrays. A combination of innovative design and SiGe Bi ...

It is the intent of Hittite through this proposal to explore the feasibility of using chemical vapor deposition (CVD)-diamond as a passivating layer within the junction of a Gallium Nitride (GaN) microwave transistor. CVD-diamond being a material with very high thermal conductivity, and being located as close as possible to the heat dissipation source, will have the effect of reducing junction tem ...

Two approaches to high performance base plates for advanced thermal management applications are proposed. Inexpensive high performance Al/Gr composites have been developed with a quasi-isotropic thermal conductivity (TC) of 600 to 750 W/mK and corresponding thermal expansion (CTE) of 7 to 3 ppm/K. CTE matching base plates for advanced multi-channel phased array radar systems enable hard (solder) ...

This proposal addresses the NGA SBIR program objective to develop and demonstrate GPS receiver improvements for ground users to provide significant “high-sensitivity” signal tracking performance over conventional military GPS receivers. The proposed system consists of (i) the Mayflower “NavAssure” SAASM GPS receiver; and (ii) receiver software signal processing enhancements, in order to m ...

Without the means for stabilizing the scale factor and bias of MEMS gyroscopes and accelerometers, they cannot become precise and accurate instruments. With stabilization, however, autonomous navigation is possible and GPS reliability can be improved. We propose to introduce active stabilization methods and test devices and carry out the proof-of-concept tests during Phase I. We will make use of e ...

A novel broad bandwidth modulator is proposed that has the potential for reducing link size by a factor of 75 and link dc power by a factor of 50. The novel modulator will also permit more environmentally robust packaging than has been possible with conventional electro-optic modulators. Finally the novel modulator is projected to permit even lower noise figure links – 3 dB – without any elec ...

Physical Sciences Inc. (PSI) and its team member Aerojet, propose to mitigate slow cook-off violence by adding a thermally-decomposing trigger to a propellant formulation to provide a benign ignition mechanism for large diameter SRMs. Physical Sciences and Aerojet have identified a potential furazan replacement for ammonium nitrate (AN) which eliminates the significant problems of AN such as hygro ...

A novel method is proposed to model the aerodynamic lift and drag coefficients for complex fragment shapes resulting from the impact of Missile Defense Agency (MDA) interceptors with target vehicles. The force coefficients are needed for the entire spectrum of flight velocities and impact altitudes ranging from low-earth orbit to near-ground. Our Phase I approach considers a high altitude model ...

It is proposed to develop a multifunctional IM compliant, filament wound composite case for slow cookoff, bullet and fragment impact. In phase I, the proposed investigation will focus upon developing our composite case, conducting slow cookoff tests, and to filament wind one case design to a subscale analog MDA rocket motor. We propose to establish a fabrication technique that will be applicable a ...
