AbstractPossible application of a retarding-field velocity-sorting process to detection in a microwave receiver was investigated. The receiver consisted of a double-ended backward-wave oscillator operating as an autodyne. Operating parameters of the receiver such as dynamic range, electronic tuning, stability, and sensitivity were measured and the results compared with those obtained from a similar autodyne receiver using an external crystal detector. It was found that the velocity-sorting detector is equal to the crystal type in sensitivity and nearly equal in dynamic range, but inferior in gain stability. The poor gain stability is due to the variation of detection efficiency with beam current, which is inherent in a retardin-field detector.
