The figure-of-merit form of the sonar equation causes a bias in calculated broadband-detection ranges. The bias is caused by the necessity of treating the figure of merit as if it were concentrated at a single frequency, since only single-frequency--transmission-loss graphs are practically available. A signal-excess form of the sonar equation is used in this report to remove the bias from passive, broadband, aural, detection-range calculations. Author
