A quasi-optical millimeter wave transmitter and receiver array for measurements of angular scintillation

Abstract

This system, used to measure the effects of atmospheric turbulence at frequencies between 116 and 173 GHz, comprises a front-fed, off-axis parabola transmitting antenna located 1.4 km from a receiver array. The five antennas in the latter receive local oscillator power from a phase-locked klystron source via a low-loss lens beam waveguide distribution system.
