Jamming and Counter-Countermeasures
Chi‐Hao Cheng, James Tsui · River Publishers eBooks · 2022
One intercept receiver is used to receive radar signals from all different types of radar for the electronic warfare processor to identify. The jamming signal must be amplified and sent to the threat radar. Some radar can be jammed easily, but some are more difficult to interrupt. The main goal of jamming is to protect the aircraft. Barrage jamming covers a broad bandwidth, so its chance of jamming a radar is high, but most of the jamming power will be wasted. The goal of deceptive jamming is to deceive the radar with erroneous information. A successful spoofing requires jamming a radar without alarming the radar operator. One of the important radar parameters the intercept receiver needs to measure is the signal’s angle of arrival. All active electronic warfare operations are inherently dangerous because emitting radio signals can potentially be self-exposing and jamming, especially self-protection jamming, is no exception.
