K-Band Echo Line

Abstract

An echo line is a long waveguide in which the radar pulse re-echoes producing a series of pulses on the indicator for test purposes. The fabrication and testing of an 18inch helix of an oversized K-band waveguide 150 ft long are discussed. Tests showed the attenuation to be 0.029 dh/foot, which suggests the use of such oversized waveguide for radar transmission lines.
