Lobe Sweep Interferometers for SECEDE 2

Abstract

Two pairs of twin-element, lobe-sweep radio interferometers were designed, constructed and bench-tested for the SECEDE II transmission experiments. One pair operates at a frequency of 145.7644 MHz, the other at 437.2932 MHz. The total of four interferometers are realized with three circularly polarized, broadband log-periodic antennas spaced equally along a two hundred meter baseline with the center antenna common to each interferometer pair.
