    RESEARCH EXPERIENCE

    University of Massachusetts at Amherst, 2007-present

     

    ·         Integration of  phased-array radar sub-systems (Nov. ‘11 - present)

                         I currently work with a team of Engineers who have been responsible for development of various sub-systems on a phased-array radar project. I am responsible for integration of the data-acquisition code with an FPGA-based control subsystem.  Using an in-house near-field scanning facility as a diagnostic, I am assembling  the passive antenna array with a radome and transmit/receive modules.

     

    ·         Simulation of a phased-array spaced-antenna radar (July ‘10 - present)

                          I developed a monte-carlo based phased-array radar simulator  using IDL – a Fortran-based programming language similar to MATLAB. I used this simulator to investigate spaced-antenna wind estimation algorithms to retrieve 2-D wind fields using an X-band phased-array radar.

     

    ·         Lead Engineer for an  X-band radar during VORTEX2 (May. ‘09 – July ‘10)

                          I lead a small team of Engineers for operation and maintenance of an X-band radar in $10M dollar field experiment. The field experiment  spanned about 2 months a year, where we would nomadically roam the great plains of central western USA on a pickup truck with our radar mounted on. I was also responsible for quality controlling the collected data and sharing them with collaborators.

     

    ·         Design and development of a solid-state pulse compressed radar (Aug. ‘08-  Apr. ‘09)

                         I lead a small team of Engineers to develop and integrate various sub-systems on a low peak power solid-state radar. The sub-systems developed were real-time data acquisition software that implemented pulse-compression, FPGA-based control system and the RF sub-system. This system is now being integrated with the phased-array antenna system.

     

    ·         Upgrades  on a Magnetron based dual-polarized radar  (Jun. ‘07 – Jul. ‘08 )

                   I developed a voltage-translator PCB using Cadence Allegro to replace an already existing but problematic component on the radar. I also upgraded the FPGA sub-system to a state machine based controller. I was also responsible for field experiments that with this radar, and subsequent data processing and quality control.

     

     

    University of Colorado at Boulder, 2004-2007

     

    ·         Temperature retrieval from meteor echo decorrelation times  (Jun. ‘06 – May ‘07)

                  Investigated algorithms to extract upper atmospheric temperature from  radar echo decorrelation times. This involved programming using IDL and presenting results at a conference.

     

    ·         Design and testing of receiver sub-system for a VHF radar  (Feb. ‘05 – May. ‘06)

                  I was responsible for the design and layout of a VHF  receiver sub-system on a PCB using Cadence Allegro. I also assembled and tested the PCB and packaged it using machining tools available in house.
