Radar — EA
Information on EA
EA , previously known as electronic counter
measures (ECM), is conducted on radar systems to reduce or
prevent the radar’s use of the electromagnetic spectrum effectively. This
chapter investigates the process of performing EA,
reviews the major EA tactics that can
be employed and then reviews the major EA tools available to the operator.
Enemy sensors are the main
focus of EA action. Active sensors are
particularly vulnerable as these sensors are designed to transmit and
receive electromagnetic energy. EA tactics and tools
look to exploit active sensors by analysing the transmission (ES)
and then attacking the receiver.
EA can be
conducted against all electromagnetic systems including communications systems. The coverage
of EA in this text is limited
to radar EA. Radar systems are operated
to detect, acquire and track targets with the ultimate view
to engaging and destroying the target. To that end, interfering
and degrading the performance of radar systems is often of
critical value to the targeted platform’s survival and ability to
carry out its intended role.
