• Kalman filtering, particle filtering, and multi-hypothesis tracking.
• Machine learning and optimization for optimal control.

RF propagation and signature modeling:

• Link budgets, terrestrial and free-space propagation models, multipath, non-stationary propagation environments (Doppler spread), clock stability and phase noise, and target kinematics.
• Antenna pattern estimation.
• Estimation of bistatic RCS.

Sensing:

• Sparse array processing, beamforming, direction finding, filtering and tracking.
• Range-Doppler radar and synthetic aperture radar (SAR).
• Signal classification and recognition.

Physical-layer communications:

• Modulation techniques and tradeoffs, channel estimation and tracking, MIMO communications, equalization, forward error correction and decoding.
• LPX waveform design.
• Multi-user detection.

Qualifications You Must Have:
