Abstract : This report covers results of a contract to provide for a rapid and accurate alignment procedure of troposcatter antennas. An experimental model embodying a microprocessor based computation routine at the receive antenna and a stable transmitted frequency allows for alignment of antennas along the great circle path. The test data shows that an alignment accuracy of better than plus or minus 1/3 degree or approximately plus or minus 1/10 of a beamwidth could be accomplished in approximately 10 minutes.
