System Transversal Equalizer.
Abstract
The report describes the implementation, theory of operation, and performance of an adjustable, 48 tap, surface wave transversal equalizer designed for the Rome Air Development Center, Floyd Site Radar. The transversal equalizer achieves equalization of system distortion by an array of fixed taps which provide leading and lagging echoes of the main signal. Equalization is achieved by the introduction of an equal but oppositely phased echo of the main signal. This cancelling echo is continuously adjustable in amplitude and phase by front panel controls. The equalizer is capable of suppressing distortion echoes, having amplitudes up to 15 dB below the main signal, to a -40 dB level. The sidelobe level reduction applies to all echoes occurring within a 20 microsecond range window. (Modified author abstract)
