AUTOMATIC TRACKING WITH SEQUENTIAL LOBING.
Abstract
This report analyzes the problem of automatic tracking with a passive RF system by sequential lobing of antenna beams. The analysis is general enough to be applied to optical, infrared, and sonar passive tracking systems. Among the problems considered are (a) processing of tracking-error waveforms, (b) demodulations techniques, (c) antenna-beam gradient and resolution, (d) pulse detection, (e) the lobing rate, and (f) receiver AGC requirements. The conclusion drawn is that the sequential-lobing system, compared to the conical-scan system, is as accurate, has the advantage of a variable lobing rate, and can change antenna beams electronically, but its signal-processing circuitry is more complex. Results of the analysis were applied to the development of wideband (50 to 500 Mc and 1 to 11 Gc) sequential-lobing tracking systems. (Author)
