Three of them are based on using the Doppler effect
and the fourth – on registration of the electromagnetic field “profile” by the
spaced receivers. It is shown that, unlike the well-known techniques
(interrogation and noninterrogation ones) the
suggested techniques have a number of advantages.

Comparison
of Results of the Water Area Survey Carried out by the Shipborne and Towed
Magnetometers. V.
A. Blednov – Navigation and Hydrography. – 2014. – No. 37. – Ð. 51–58.
The results of determining the angular components of
the Earth¢s magnetic
field carried out on board the moving ferromagnetic object (vessel) are
compared with magnetic field measurement data obtained by towed magnetometer.
