Identification of a Ship or Submarine from its Magnetic Signature

The relationship between the measured time fluctuations of the ambient magnetic field due to the passage of a ship or submarine and the characteristic magnetization properties of this vessel are derived. This relationship would be useful in identifying or classifying ships and submarines according to their magnetization properties.     

Model for Spectral and Polarization Characteristics of Chaff

A stochastic model which describes the spectral and polarization characteristics of radar echoes from a chaff cloud consisting of a collection of rotating dipoles, which may have either completely random or preferred orientations, is presented.
