2. Direction finding
2.1 Principles and notations
A direction finder measures the direction of arrival of an electromagnetic wave relative to a reference direction. The process is purely passive and undetectable by the transmitter.
Whatever their principles, conventional direction finders all use the assumption of planar wavefronts associated with each transmitter: the isophase (i.e., constant-phase) loci of the wave emanating from a transmitter are assumed to be parallel planes at sufficient distance from the transmitter (i.e., beyond the Fresnel distance
