Intrepid Tiger pods onboard a Reaper would allow the Marine Corps to conduct missions such as "jamming, deception jamming
to try to confuse the radars,...
The noise jamming conceals the target signal with the intentionally radiated noise-like signal and the deception jamming
deceives the tracking system of radar with the false information about the critical intelligence such as range, angle, or velocity of target.
Angle deception jamming
is a significant electromagnetic interference for monopulse radar seekers, which is in the same range unit and beam unit with the target, and making the seekers track to themselves but notthe real target.

It seems that the most effective solution is the use of laser-based IR jammers for deception jamming
or simply to destroy the vulnerable parts of a missile's IR seeker.
One form of deception jamming
uses previously recorded signals.
When used for real time deception jamming
, a frequency memory loop is brought into play.

scenarios," in Proceedings of the IEEE Radar Conference, pp.
The SPS-141 jamming pod provides deception jamming
, affecting the range and azimuth display of the threat radar.
The A.100 has 360|degrees~ coverage in azimuth in both transmit and receive modes and is capable of generating 14 deception jamming
, nine noise jamming, eight Doppler jamming and six combination jamming modulations plus a multimode feature which allows the system to run four pre-programmed modes sequentially.
Jamming may be performed by a transmitter that either swamps the enemy transmitter (i.e., noise or brute-force jamming) or produces misleading information (deception jamming
), creating false targets or breaking radar tracking.
is primarily a countermeasure used against search and tracking radars.
