Li, "ECCM scheme against interrupted sampling repeater jammer
based on time-frequency analysis," Journal of Systems Engineering and Electronics, vol.
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.
More sophisticated is the repeater jammer
, which captures and then re-radiates a portion of the enemy's transmission.
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.
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.
One is a stand-alone, high-power, data-linked repeater jammer
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).
* exploitation of the minimum delay time through the repeater jammer
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.
The four-year cycle of reinventing the repeater jammer
concept, which extends back to 1944, will have finally been broken.
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.
However, an active repeater jammer
operating from a towed decoy can radiate at the radar frequency while replicating, precisely, the radar waveform.
