PASS Program Report: Millstone Test Analysis - 61 Module Array System.
Abstract
During in-water tests at the NUSC Millstone Test Facility, the designed signal generator, beamsteering electronics, and power amplifiers were used to drive the 61-module array. The signal generator employed a unique digital technique to pulse-width modulate a square-wave carrier, producing two intense primary frequencies in the water suitable for parametric generation of the difference frequency. The ability to produce 3 different modulation waveforms and to chirp the modulation frequency was also demonstrated. In addition, electronic beamsteering using the APL digital shift-register design was demonstrated between angles of plus or minus 45 degrees without appreciable degradation of the primary beam pattern.
