The reduction in false alarm probability PFA 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 SN is reduced with increasing n in such a manner as to maintain a constant detection probability, PC. Decreases in PFA as great as 0.19 were observed. To obtain a minimum PFA while retaining constant PC, a greater number of echo cycles are required for the initially smaller values of SN for n 6.
