Abstract:

The completion of the master console for the airborne four-frequency radar system, to be used in NRLs wavepropagation studies, was assumed by NRL and was described previously see AD-409 128. Four displays were incorporated into a single console, along with the transmitter, receiver, and antenna-drive control functions. Two cathode-ray tubes present the B and PPI scans, while a third presents dual traces representing linear A sweeps. The initial design required 1.2 kw at 400 cps, lacked adequate display linearities, and presented maintenance problems when installed aboard aircraft. The new console design uses transistor and vacuum-tube modular units. Power requirements were reduced to 14 of that used in the original console. Video-amplifier rise times of less than 35 nanoseconds were achieved using transistor circuits. Display distortion and defocusing were materially reduced, and all gain controls are linear. Author
