The most important method to counter radar jammers is operator training. Any system can be fooled with a jamming signal but a properly trained operator pays attention to the raw video signal and can detect abnormal patterns on the radar screen. The best indicator of jamming effectiveness to the jammer is countermeasures taken by the operator.
The jammer's continuous transmissions will provide a clear direction to the enemy radar, but no range information. [1] Deception may use a transponder to mimic the radar echo with a delay to indicate incorrect range. [1] Transponders may alternatively increase return echo strength to make a small decoy appear to be a larger target. [1]
The signal loss inherent in a cross polarized (transmitter different from receiver) pair is 3 dB for dissimilar types, and 17 dB for opposites. Aside from power loss to the jammer, radar receivers can also benefit from using two or more antennas of differing polarization and comparing the signals received on each.

The R-330Zh Zhitel is a mobile truck-mounted electronic warfare jamming communication station, manufactured by NVP Protek and fielded by the Armed Forces of the Russian Federation (AFRF). [1]
Vietnam jams the Vietnamese service of Radio Free Asia, [33] Radio Đáp Lời Song Núi, [34] some FEBC [35] programs, mostly in Vietnamese minority languages as well as Radio Sweden [36] with a "siren" jammer and "bubble" jammer on FM frequencies. In Nigeria, the Nigerian Broadcasting Commission has claimed it jams the signal of Radio Biafra ...
A DRFM system is designed to digitize an incoming RF input signal at a frequency and bandwidth necessary to adequately represent the signal, then reconstruct that RF signal when required. The most significant aspect of DRFM is that as a digital "duplicate" of the received signal, it is coherent with the source of the received signal.
"The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There ...
