The article reports that Italian researchers are making breakthroughs in passive radar technology, opening the door to detecting previously hard-to-track targets such as stealthy aircraft. The Italian work is being driven by Finmeccanica, Elettronica and several academic institutions. North Atlantic Treaty Organization's Consultation, Command and Control Agency is also involved by supporting the multi-static passive radar activity. An active radar system sends out radio-frequency energy and waits for the returns to track a target. The passive system needs to know the location of the emitters and measures the general electromagnetic environment when it's not disturbed by a target flying in an area.

This article reports on three companies being asked by the U.S. Navy to design an aircraft that can conduct simultaneous intelligence-gathering missions. Specifically, the Navy wants a single, EPX aircraft that can use a powerful radar and at the same time operate an array of sensitive receivers that can collect faint electronic emissions or communications from hundreds of miles away. The multisource information would be fused to locate and identify objects of interest.

The article discusses issues related to the U.S. National Reconnaissance Office (NRO) Future Imagery Architecture (FIA) program. According to the article, the Boeing/NRO imaging radar that failed shortly after launch creating a falling debris risk indicates that trouble within the FIA program has spread to the radar side of the secret project. Air Force General Victor E. Renuart Junior said that there does not yet appear to be much concern about sensitive technologies on the satellite falling into enemy hands.

This article states that Northrop Grumman boasts that its bid for the U.S. Navy's Broad Area Maritime Surveillance (BAMS) competition is the only one to actively execute end-to-end testing. Central to the company's proposal for the high-profile program is its Multi-Function Active Sensor, a 360-deg. radar capable of identifying and tracking ships. Together with the Boeing P-8A Multi-Mission Aircraft, BAMS will replace the Navy's P-3 surveillance fleet. The BAMS program is worth $2 billion and Boeing and Lockheed Martin are competiting for the project.

This article reports that the supposedly dead joint unmanned combat air systems (J-UCAS ) program spawns new designs as unmanned combat becomes focus for planners. The parting of the ways between the U.S. Air Force and Navy over the J-UCAS program has triggered a surge in new competition and plans for large, long-endurance aircraft. A number of aerospace companies are looking at designs with multiple engines, wingspans of more than 100 ft. and the potential to generate the power needed for directed-energy weapons or large, active electronically scanned array radars. The latter can produce pulses of microwaves intense enough to serve as weapons.

ADS-B.0 is a surveillance system that broadcasts an aircraft's GPS-derived location to a receiver on the ground. A network of 28 ADS-B ground stations being installed by Thales in Australia will provide tracking capability in vast areas where there is currently no radar capability.

This article focuses on how the air war in Iraq has changed from one primarily of bombing to that of intelligence-gathering, surveillance and command. At night, from 31,000 ft. over Iraq, radio chatter records the pulse of military operations. It can offer the pace of a well-written novel by shifting quickly through rapid decision-making, unexpected danger, boredom and fear that escalates into terror. During hot-weather periods, the small JT3D engines can limit the E-8's operational altitude to significantly less than the desired 31,000 ft., which reduces the radar's footprint to less than the surveillance crew would like.

This article presents information regarding air traffic control radars. It gives information including designation, description, applications and remarks about the radars.

The article reports that F-15C fighter pilots of the 12th and 19th squadrons are flying the radar of the future. It uses sensor technology that is to be operational on the F/A-22 Raptor, F/A-18E/F Super Hornet, F-35 Joint Strike Fighter and upgraded F-15E Strike Eagle. The radar's performance numbers are classified, but the new Raytheon APG-63(V)2 radars, the first that are operational with active electronically scanned arrays, can see a small cruise missile or an airframe with stealth shaping at around 50 minutes, the distance at which the standard F-15C radar would see a manned-fighter target. The subscale, cruise missile-like targets that pilots practice against are 12-14 ft. long while an Su-27 is about 72 ft. long and a MiG-29, 57 ft.

What some Defense Department planners regard as the U.S.' most compelling future threat—an attack by cruise missiles carrying chemical or biological warheads—is pushing development of a true "network-centric" warfare system. New electronically scanned, multifrequency radars pick low-flying, stealthy cruise missiles out of ground clutter. The electronic babble produced by signals ricocheting from buildings and broken terrain has traditionally helped protect low-flying missiles and aircraft from radar detection. What really makes cruise missile defense possible is the staple of net-centric operations and warfare: automated decision-making aids, machine-to-machine links, automatic target recognition, open electronics architectures, multi-frequency sensors and advanced horizontal communications—all of which break down barriers.

The majority of new military electronics programs during the year 2003 have addressed intelligence, surveillance and reconnaissance (ISR), fueled by the increasing importance of time-critical targeting for conflicts in Afghanistan and Iraq, and the new surveillance demands of Homeland Security. Initial systems design work was split 50-50 between Northrop Grumman and Raytheon, with Boeing added as an equal partner for the Weapon Systems Integration (WSI) contract awarded in March 2003. Synthetic aperture radars will account for more than half of the total U.S. airborne reconnaissance sensor budget throughout the decade, with U.S. funding alone providing almost $1 billion per year.
