A discussion of problems in the passive detection of submarines by single, nondirectional hydrophones. Assuming the signal emitted by a submarine to be a broadband noise with characteristics similar to background noise, detection is possible because of the increase in noise power caused by the presence of the target. The author analyzes the effects of the motion of the submarine past the hydrophone and the uncertainty in background noise level, and finds that detectability is essentially independent of observation time if there is uncertainty about background noise. Hence a faster and noisier submarine is more easily detected than a slower and quieter one. If background noise is stationary, however, the nonstationary noise of the moving target can be used by the detector to estimate background noise and thus increase detectability. 76 pp. Bibliog.
