Circuit modeling and optimization techniques for next-generation radar.

Spectral emission requirements for radar systems are becoming increasingly strict. Future radar systems will require well-designed, reconfigurable circuitry to coexist with the myriads of wireless devices using the spectrum. There are two main goals of this research. The first goal is to demonstrate circuit optimization algorithms implemented in real-time with two types of fast tuners. The optimization algorithms can tune the fundamental tuning elements of the tuner to quickly find an efficient operating point for the power amplifier while staying within spectral constraints. Secondly, this thesis presents a new method to model wideband low-noise amplifiers for use in receiver circuits using the Volterra Series. Both of these contributions are expected to enhance design and implementation of future radar systems.
