Experiments were conducted to determine the impact of Hall effect plasma thruster plumes on communication system phase noise. The tests were performed on several Hall thrusters including a T-100, a D-55 manufactured by TNIIMASH (Research Institute of Machine Building) and an SFT-100 manufactured by Fake1 Enterprises. The experiments included the use of a microwave spectrum analyzer as a receiver in a simulated microwave communication link. The phase noise level of the received signal shows a significant increase after passing through the plume of a Hall effect thruster. The level of phase noise increase is highly dependent upon the propagation path, carrier frequency and the level of thruster discharge current oscillations.
