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 electronic
protection although some EP techniques are also
designed to make adversary ES more challenging.
EP 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.
