Some specific accomplishments (Raytheon):

• Technical lead and management for the development and analysis of advanced algorithms for upgraded early warning (UHF) phased array radars (under the HAVE GOLD program: roughly $1.2 M government contract). Also analyzed a specific novel detection algorithm that makes simultaneous use of sum and monopulse channel pulse return data to increase probability of detection. Wrote report and gave presentations and opinions to the Integrated Product Team (a group of six companies working independently on algorithms under the HAVE GOLD program).
• Investigation of the optimal use of a mixture of coherent and noncoherent pulse integration (addressed specific to the HAVE STARE radar, but of more general applicability). Wrote report and made recommendations on schedule.
• Management of and participation in algorithm development efforts for Upgraded Early Warning Radars for National Missile Defense under the LSI (Lead System Integrator) program.

Solution of difficult mathematical or physical problems in all disciplines. Marketing, technical, competitive analysis, and other support for business planning initiatives. Development of university liaison relationships.

Some specific accomplishments (MicroUnity):

• Performed a feasibility analysis of an entirely new technique for transmitting and receiving cellular radio signals based on widely distributed antenna arrays. Developed a complete understanding of the approach, formed an analytical solution, and numerically simulated numerous cases to assess the challenges and benefits. The detailed investigation led to a patent disclosure, currently in the process of filing. Wrote internal report covering the full investigation, and presented results in a major internal seminar to the CEO and MicroUnity management and technical staff.
