The report presents a geophysical evaluation of the short-period LASASAAC system as it operated during 1971. The system operates in two parts. The Detection Processor DP performs data acquisition and signal detection in an on-line computer. throughout 1971 DP operated with a detection threshold of 10 db signalnoise ratio where the signal measurements are equivalent to zero to peak, and noise measurements are 28.8 second averages of filtered beams. The average DP detection rate was 450 signals per day.
