BBN Technologies solves challenging problems of high importance to our customers in the Department of Defense, the Intelligence Community and Industry by rapidly prototyping systems for sensing complex physical phenomena, correlating them to events of interest, and producing high-value, actionable information from the sensed data. Our team specializes in developing next-generation sensor system technologies by combining a fundamental understanding of the underlying EM physics including complex electromagnetic interactions and signatures, and propagation phenomenology, with a deep expertise in analysis, statistical signal processing, optimization, and machine learning We are currently searching for a highly qualified RF Signal Processing Research Scientist to join our team in Arlington, VA or Columbia, MD. Desirable candidates will have experience deriving and implementing research-grade algorithms and applying these to data collected from real sensors. Qualified candidates will have academic or professional experience in several of the areas listed below.

What You Will Do

The position requires routine onsite presence at our Arlington, VA or Columbia, MD offices

Statistical signal processing:

• Estimation techniques including Bayesian and non-Bayesian estimators, performance measures such as bias and mean-square error and bounds on estimator performance such as the Cramer-Rao lower bound.
• Detection techniques including the Neyman-Pearson detection, probabilities of detection and false alarm, receiver operating curves, etc.
• Cyclostationary signal processing:

• CAF, SCF, SOF estimation.
• Computation of Cyclic Cumulants.
• Cyclic Feature Detection.
• Adaptive signal processing:

• Temporal and space-time adaptive processing.
• Interference covariance estimation techniques including both structured and reduced-rank techniques.
• Wiener filtering and on-line adaptive techniques such as LMS and RLS.
• 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.
