ECCM components.
(a) An example is terrain masking, where a friendly radio station
is placed so a hill is between it and the enemy.
(b) Another example is avoidance by using a directional antenna.
(2) Anti-ECM are used against jamming. They cannot be used against
deception or ESM. This involves actions taken after learning the enemy is
using EW against friendly forces. Effective anti-ECM methods are:
(a) Determining the cause of interference.
(b) Recognizing
the
difference
between
jamming
and
natural
(c) Reporting incidents of ECM so the jammer can be located and
destroyed.
(d) Using techniques to overcome ECM.
Continue
to
operate
normally
to
encourage
jammer
retargeting.
Improve the signal-to-jamming ratio by adjusting
the
receiver, increasing transmitter power, adjusting
the
antenna, and setting up a retransmission capability.
(e) Changing frequencies.
(f) Shutting down communications and using alternate frequencies.
This is done as a last resort.
