Radio frequency jammers are devices that interfere with communications systems, usually by sending out competing radio signals to confuse nearby electronics. ... sale or offer for sale of jamming ...
The prototype KAKTUS set in the KAKTUS-MO version (operational module) was developed in the years 2007–2010 by a consortium consisting of: the Institute of Communication of the Faculty of Electronics of the Military University of Technology, the Military Institute of Communications and the companies WITPiS, KenBIT, Thales, Rodhe&Schwartz, Bonn Elektronik, Poynting, Transbit, WAREL, Jelcz S.A ...
The system is highly automated which reduces operator interaction. The system draws up to 36 amps of vehicle power, weighs approximately 69 lbs, and measures 13″H × 14″W × 19″D. Vehicle Jammer System STAR V: Protective modular jamming system STAR V 740 is intended for a protection against RCIED. The system either prevents the activation ...
As opposed to analog "memory loops", there is no signal degradation caused by continuously cycling the energy through a front-end amplifier which allows for greater range errors for reactive jamming and allows for predictive jamming. A DRFM system may modify the signal prior to retransmitting which can alter the signature of the false target ...
In some cases, jamming of either type may be caused by friendly sources. Inadvertent mechanical jamming is fairly common because it is indiscriminate and affects any nearby radars, hostile or not. Electronic jamming can also be inadvertently caused by friendly sources, usually powerful EW platforms operating within range of the affected radar.
DARPA's Precision Electronic Warfare (PREW) project aims to develop a low-cost system capable of synchronizing several simple airborne jamming pods with enough precision to replicate the directionality of an electronically scanned antenna, avoiding collateral jamming of non-targeted receivers.
The Mobile Ground-to-Air Radar Jamming System (MGARJS) provides electronic warfare field support capability to protect high-value targets and installations. The MGARJS consists of mobile stations placed strategically about high-value installations.
An ALQ-144 jammer mounted on an OV-10 Bronco.. The AN/ALQ-144, AN/ALQ-147, and AN/ALQ-157 are US infrared guided missile countermeasure devices ().They were developed by Sanders Associates in the 1970s to counter the threat of infrared guided surface-to-air missiles like the 9K32 Strela-2.
