Abstract

The advent of high-speed large gate-count Field Programmable Gate Array (FPGA) components facilitates the implementation of high-performance parametric digital waveform generators for radar applications. One such waveform is the popular Linear-FM chirp. The state-of-the-art allows us to generate high-fidelity precision wideband Linear-FM chirp waveforms with relative ease, and furthermore enhance these waveforms with a number of features including spectral notches, phase equalization, compound pulses, and more. Design equations are presented as well as a number of feature enhancements.
