A Study of the Decrease in False Alarm Probability Resulting from an Increase in the Number of Displayed Echo Ranging Cycles.

Abstract

The reduction in false alarm probability P(FA) as the number of displayed echo cycles n is increased from 6 to 12 is investigated. According to a predetermined experimental curve, the value of S/N is reduced with increasing n in such a manner as to maintain a constant detection probability, P(C). Decreases in P(FA) as great as 0.19 were observed. To obtain a minimum P(FA) while retaining constant P(C), a greater number of echo cycles are required for the initially smaller values of S/N for n = 6. (Author)
