The main aim of EP , previously
known as electronic counter counter measures (ECCM), is to ensure
continued friendly use of the electromagnetic spectrum despite adversary EA
and ES. Countering EA efforts is the main focus of
EP although some EP
techniques are also designed to make adversary ES more challenging.
and EA fields tend to be complimentary and reactive fields
of endeavour in that an advance in technology and techniques
in one field necessarily results in research, development and advancement
in the other.
The designers of military radar systems must assume
that their systems operate in the most hostile of electronic
environments and must, therefore design the radar with EA and
EP in mind. EP
is not solely a military concern, however. Civilian radar systems
also have to operate in hostile electronic environments and must
therefore have EP built in. The civilian environment is often
hostile due to the operation of other radar and electromagnetic
systems in the same physical location as the radar system.
EP techniques developed for the military domain
can allow civilian radars to operate in the presence of
other sources of potentially disruptive electromagnetic energy.
