Novel technique for antenna gain measurement in satellite earth stations

A novel technique is proposed for the measurement of the gain of antennas used in earth stations involved in satellite communications. In principle the technique requires a standard-gain reference antenna, automatic level control over a satellite loop, and narrowband detection techniques. Advantages over conventional techniques (line-of-sight or radio star measurement) are claimed including stable received flux, measurement in situ at operational elevation, accurate crosscalibration with other earth-station antennas, and removal of the influence of propagation on the signal level.
