An Experimental Radar Facility to Study Backscattering from the Wakes of Hypersonic-Velocity Projectiles

Abstract

A coherent, CW, superheterodyne radar system operating at frequencies of 9, 17, 35 and 70 GHz is described. The radars are installed on a free-flight range to study backscattering from wakes of hypersonic-velocity projectiles. Each radar is equipped with a focused-lens antenna oriented at an angle of approximately 45 degrees to the flight axis. Amplitude and phase of the received signal are recorded separately. Some typical results are given to demonstrate the capabilities of the equipment.
