Doppler simulator for moving target simulation in X-band radar applications

John Phillips, University of Rhode Island


This thesis covers the design and implementation of a Doppler Simulator for use in testing X-band radar systems. When testing the effects of Doppler shift in radar systems, it is often not practical to use moving targets. Having hardware that remains stationary while providing the equivalent Doppler shift of the moving target would be advantageous. The Doppler Simulator designed for this thesis will allow a wide range of speeds to be simulated from a single stationary unit, as well as provide a controlled simulated speed for repeatability of radar measurements, which cannot be obtained with actual moving targets. This thesis covers the concept of the Doppler Effect and how it affects a signal, as well as the design of a circuit which can simulate this effect in hardware. The end result of this thesis is a product that can be used to simulate Doppler shift in radar testing.^
