Detection of ultrawideband pulses in atmospheric turbulence and Gaussian noise

Abstract

Scintillation of electromagnetic energy traversing the atmosphere is caused by refractive index inhomogeneities in the transmission path that cause phase shifts, giving rise to selective reinforcement or degradation of the energy across the beam. It is the object of this paper to determine the detection probability and false alarm rate for pulses of electromagnetic energy of varying width in the presence of atmospheric turbulence and Gaussian noise.
