Description
Summary:In this paper, a simple method of passive range measurement is discussed. The receiver system can be either hydrophone or horizontal array. Unlike earlier methods of passive source range measurement, we mainly consider the phase information of the passive source, rather than the amplitude. The method only uses the simplest principle range=velocity time. The key of the method is how to acquire the partial deviation of the phase with respect to radial frequency and measurement variables. In physics, the former is equal to time, which can be obtained from the spectrum of the source. The latter is equal to group velocity, which can be evaluated according to the environmental variable, such as water depth, sound profiles, bottom quality, etc. In fact, measurement variables can be substituted by the sound speed in water over the bottom; the error is no more than 8 percent.
