Signal Processor Performance Comparison.
Abstract
The performance of several signal processors used or potentially useful in modern active sonar has been investigated. This report compares these processors on a basis which includes both the output statistics and data rates. These comparisons are based on what are referred to as modified ROC curves, which give probability of detection vs threshold crossing rate. A family of these curves, one for each input signal-to-noise ratio, is required to describe each signal processor. Initially, two sets of signals were passed through each of the processors under consideration. The first set consisted of ideal signals for that processor and the second set consisted of composite signals which were formed by adding three overlapped ideal signals with 20 milliseconds delay between components. In the remainder of the discussion these will be referred to as ideal triplets. The results for both the ideal signals and the ideal triplets are shown. Each processor is discussed briefly.
