repeater jammer

[ri′pēd·ər ‚jam·ər]

(electronics)

A jammer that intercepts an enemy radar signal and reradiates the signal after modifying it to incorporate erroneous data on azimuth, range, or number of targets.

A Method against Interrupted-Sampling Repeater Jamming Based on Energy Function Detection and Band-Pass Filtering

Our ideas for the deception scheme crystallized around a small, simple, and cheap repeater jammer, which we called the DAJ [Distributed Area Jammer], which would fit on a telegraph pole and run off main power.

First person ... singular

More sophisticated is the repeater jammer, which captures and then re-radiates a portion of the enemy's transmission.

When Weapons Cheat

It then uses signal algorithms on a 386 chip to determine whether it is incoming or outgoing and employs a repeater jammer to send a signal back to the shell, causing it to be detonated at a much higher elevation.

Additional Mortar Jammers Ordered

The Elta EL/L8260 attack helicopter self-defense system can include the EL/L-8231 small aircraft CW repeater jammer. The Bofors/Rodale ALQ-167 Yellow Veil noise or deception jammer remains on Royal Navy Sea Kings HAS-6 and can be carried in a pod on the Lynx.

Rotary wing EW - more than survival

One is a stand-alone, high-power, data-linked repeater jammer version.

Self-protection calls for a tow

The Southwest China Research Institute of Electronic Equipment (based at Chengdu and Guanxian in Sichuan Province) offers the land-based I/J-band BM/DJG 8715 radar jammer (Chengdu facility); the E- through J-band BM/HZ 8610 surface-ship ESM (Chengdu); the E/F- and the I/J-band BM/KG 8601 airborne repeater jammer (Chengdu); the I/J-band BM/KG 8605 and I-band BM/KG 8606 airborne noise jammers (Chengdu); the C- through J-band BM/KJ 8602 RWR (Guanxian); and the D- through J-band BM/KZ 8608 airborne ELINT system (Chengdu).

Trends in electronic counter-countermeasures

Airborne systems include the 1- to 18-GHz BM/KZ 8608 ELINT system, the GT-1 chaff/IR decoy flare dispenser, the 0.7- to 1.4-GHz/2- to 18-GHz BM/KJ 8502 fixed-wing RWR, the BM/KG 8601 E/F- and I/J-band repeater jammer, the BM/KG 8606 I-band radar jammer, the BM/KG 8605 I/J-band noise jammer and the BM/KG 8605 I-band radar jammer.

Emerging industries and markets

The four-year cycle of reinventing the repeater jammer concept, which extends back to 1944, will have finally been broken.

The two evolutions in electronic warfare

Looking at these companies in turn, Elta has a product range which spans such equipment as the EL/K-1150 series COMINT receivers; the EL/K-7001 20-500 MHz land mobile COMINT/comms jamming system; the 20-500 MHz EK/K-7032 airborne COMINT suite; the EL/L-8202 F- to J-band pod-mounted radar jammer; the EL/L-8230 G- to J-band dual-mode, internally mounted radar jammer; the EL/L-8231 H/J-band internally mounted repeater jammer; the EL/L-8240 internally mounted EW suite (an off-shoot of Lavi technology?); the EL/L-8300 airborne strategic SIGINT suite and the EL/M-2160 pulse Doppler missile warner.

NATO EW - at the turning point

However, an active repeater jammer operating from a towed decoy can radiate at the radar frequency while replicating, precisely, the radar waveform.
