Detection of Surface Electromagnetic Effects.
Abstract
The object of the research was mainly to develop means for detecting underwater objects through their effects on surface conditions. There are many surface disturbances caused by a submerged object which are large enough to be easily measured; however, in almost every case there is a corresponding natural random disturbance which would mask the desired 'signal.' The problem thus is one of filtering the signal from the background noise, and it is the theory of one such filter that is described here. Some experiments conducted in a ripple tank are also described, and a brief discussion of some practical aspects of use under actual sea conditions is included. (Author)
