PROFESSIONAL EXPERIENCE

BMDS Analyst

Confidential

Responsibilities:

• Integrated objected - orientation RCS time domain (SC extraction from propriety finite method solver) into our radar scene simulation
• Created objected-orientation RCS frequency domain model from chamber measurements including determine the type of gimbal positioner from the raw data and remap the line-of-sight to the coordinates used by our radar scene simulation, and created the tool to check the output by computing the estimated object length using iFFT.
• Aided development of Post-Intercept Debris RF Algorithm based on the Hough Transform by experimenting track filters by detection probability(erf function), masks(likely KV debris tracks) and regression methods to reduce the range-of-intercept error computing from Hough track detections.
• Experimentation with Principle Component Analysis to see if Hough parameters (slope, y-intercept) can be reduced to a single distance and use the resulted histogram to differentiate strike-angle given noise and number of debris

RF Communication Engineer

Confidential

Responsibilities:

• Assisted with SLS Core Stage Triboelectric-effect multi-pulse interference analysis on CRD (Command Receiver/Decoder), including interference pulse waveform construction using a digital synthesizer, then combining the interference signal with the command tones with a hybrid coupler and observing if the command tones are detected
• Completed NTIA (National Telecommunications and Information Administration) forms for SLS Core Stage radio frequency transmitters and antenna (included supporting data and measurements)
• Created math models for DSN (Deep Space Network) ranging signals, began preliminary link analysis to study required modulation index/residual carrier for deep space missions, and compiled notes for team lead to look over for telecom with JPL (all from DSN Link Design Handbook
• Assisted in RF telemetry trade study for Exploration Upper Stage
• Performed numerous change reviews and requirement validations for various Stages/avionics and cross-program documentation
• Provided weekly RF avionics status to Stages

Algorithm Engineer

Confidential

Responsibilities:

• Research, design, and test of indoor RTLS (real-time location systems) using two different 2.4GHz approaches:
• RSSI (Received Signal Strength Indicator) Approach:
• Utilized many nodes with multiple receivers per node (Atmel IEEE radios) with a modified Friis equation built automatically from calibration measurements, which then were used to estimate Cartesian position via an Extended Kalman Filter derived specifically for this approach.
• AoA (Angle of Arrival) Approach:
• Utilized multiple phased array nodes (in-house custom hardware including an FPGA) with adaptive equalization to estimate angle of arrival via MUSIC algorithm (Multiple Signal Classification).
• Angle data was filtered (based on the realistic motion of a pedestrian as well as signal energy/eigenvalue) and put through a least squares fit and a state estimator (Kalman Filter). The system incorporated multiple modes similar to a radar (search, track, re-acquire). Also experimented with using enumerations to determine all unique array combinations of 2 or more (scalable to N arrays) to get more data points from a single observation.
