Professional Experience
Sparton/Anti-Submarine Warfare - DeLeon Springs, Fl

ELECTRICAL ENGINEER
. Created a dynamic link performance simulation in MATLAB that included
models of aircraft motion, ocean surface motion, link equations and
other variables. Model was adopted by the Navy for use in CONOPS
development and system level trade studies. Ultimately led to
simplified RF downlink requirements that saved more than >$2 million
in aircraft infrastructure changes, and $300k annualized savings in
radio components used in disposable munitions.
. Participated in multi-national, multi-corporate datalink working group
to standardize Navy/ASW communications across NATO. This activity
included analysis of subsystem impact, waveforms, FEC performance,
code word design, and general link design of physical layer and data
link layers. Developed FPGA based PHY and MAC implementations based
on recommendations from this group.
. Designed software defined radios for high volume, low cost
applications. Implementation of full transceiver at a $25 price point
for military ASW applications. Adoption allowed the use of new,
bandwidth efficient waveforms, while maintaining backward
compatibility with legacy equipment on older aircraft. Designs are
currently being adapted for commercial products.
. Produced several radio designs of different architectures - direct
conversion(rx and tx), direct synthesis, two point modulators, super-
heterodyne, sigma delta synthesis and others.
. Assisted in design and testing of RF amplifiers in the VHF, UHF, and
1.2 GHz range. UHF amplifiers were used in a unique application that
allowed submarines to deploy buoy's from underwater and communicate to
satellites and aircraft with acoustics while remaining submerged. VHF
amplifiers were produced in high volume to support military ASW
operations.
. Pioneered Domain Specific Instruction Set Processor(DSIP) for use in
sonobuoy applications. DSIP was implemented in FPGA fabric and
included a reduced instruction set with complex (microcode)
instructions tuned specifically for the application domain - acoustic
and RF baseband processing. Development included deployment of unique
Excel-based tools for use by the layman in software development, FPGA
firmware generation, and code assembly. Tools support Verilog
generation of DSIP design, allowing rapid adjustment to core, register
file, and ALU/MAC through GUI interface. Adoption allowed task
offloading and requirements reduction of primary CSCI's while using
only "left over" resources in FPGA. Led to reduced recurring costs in
products and reduced aggregate throughput by taking advantage of
temporal and spatial data relationships.
. Participated in system testing and evaluation of sophisticated,
airborne receiving equipment designed for use in high RFI
environments.
. Led a five person research and development team.
. Planned, coordinated, and participated in field testing of designs.
Tests often included week long deployments on Naval research vessels,
and experience with space communications and ground segments.
. Acted as primary contact for several component vendors including ADI,
Freescale, Altera, Xilinx, and others. Offered staff level guidance
to several programs, coordinating hardware and software development
strategies for cohesiveness and engineering re-use.
. Championed software radio technology within the corporation, leading
to several contract awards and replacement of obsolete technology that
had persisted(for decades) due to corporate culture.
. Applied skills learned during Six Sigma Greenbelt certification in
production environment. Also applied lean concepts. Contributions
led to $150k of annualized savings through BOM, labor, and rework cost
reductions.
. Led framework development to support in-field C4 of sonobuoy's.
Framework included PA/LNA design, USRP, GNURadio, and software
development for PHY-thru-Application functionality.
. Wrote applications in Visual Studio and KDevelop for several purposes,
including: 3D visualization of deployed assets, global sonobuoy C2 via
Iridium, and RF test equipment automation for TEM/OAT.
. Cooperated with counterparts and seniors in unique joint venture with
an industry competitor. Opportunity provided many learning
opportunities in the areas of: corporate politics, technical design
debate and defense, and collaboration in sensitive subject areas.
. Provided market-oriented systems engineering for navigation products
developed and sold by commercial business unit. Included product life
cycle flow from market requirements definition to design descriptions,
test plans and production. Products included AHRS and antenna
pointing platforms.
