Passive ranging of near field targets in the audio frequency band

The use of passive ranging techniques for imaging targets situated in the near field for the audio frequency band is presented in this thesis. A three port interferometer used in millimetre waves is introduced and it is shown that with some approximations, it can be used to passively image targets i...
