The article focuses on Lockheed Martin's contract to develop the Advanced Range Threat System Variant 3 (ARTS-V3) Variable Aperture Digital Radar (VADR) system for the U.S. Air Force, aimed at training aircrew to engage with advanced integrated air defense systems (IADS) by simulating long-range, high-power surface-to-air missile (SAM) radar threats. It highlights Lockheed Martin's role in enhancing aircrew training capabilities against modern threats.

The article focuses on the survey of radar warning receivers (RWRs) and radar electronic support measures (RESM) systems, used in airborne applications. Topics discussed include the use of RWRs in the European theater, during World War II, to the introduction of radars installed on British and German night fighters; the ability of the radars to guide surface-to-air missiles (SAMs) and air-to-air missiles (AAMs) by the mid-1950s; and the advent of digital receiver technology in RWRs.

The article offers information about the pulse-Doppler radar, a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It mentions that pulses from a pulse Doppler radar are in general longer than would be the case in a non-coherent radar.

The article offers information on the radar electromagnetic attack (EA) electromagnetic protection of the radars. It further discusses use of no coherent noise jamming against a simple pulsed radar; the jammer has the advantage of jamming directly into the maximum radar receiving antenna gain; and also mentions that phased array radars can be designed with reduced gain in the antenna elements at the edges of the antenna array.

The article informs about the electromagnetic protection of mono-pulse radars that has a single antenna with a single feed. Topics include a single antenna feed reflects into a parabolic dish reflector to transmit and also receives signals reflected by the reflector; and radar's tracking ability and makes the jamming ineffective with tracking ability.

The article discusses the plans of the Great Britain's government to equip the Royal Air Force's (RAF's) Eurofighter Typhoon multirole fighter with an advanced active electronically scanned array (AESA) radar. It mentions that equipment has provide electronic warfare (EW)/electronic attack (EA) capabilities alongside more traditional air-to-air and air-to-surface modes.

The article offers information on how technology survey is taking a look at radar jammers for their introduction during World War II, radars have had a profound impact on modern warfare. Topics inlcude the radar developers are leveraging many types of new technologies especially from the commercial sector to improve radar performance, and the self-protection systems typically has focused on higher radar frequencies associated with target tracking and fire-control radars.
