Abstract

In this paper, we study the effect of phase noise on space-time adaptive processing in general, and spatial processing in particular. A power law model is assumed for the phase noise. It is shown that a composite model with several terms is required to properly model the phase noise. It is further shown that the phase noise has almost linear trajectories. The effect of phase noise on spatial processing is analyzed. Simulation results illustrate the effect of phase noise on degrading the performance in terms of beampattern and receiver operating characteristics.
