The slotted planar array is a microwave antenna, which uses hundreds or thousands of tiny slots, each slot acting as a very simple antenna element. A complex network of waveguides and delay elements hidden behind the antenna array times the arrival of the microwave signals in such a fashion, that the antenna produces a very tight mainlobe beam, and very small sidelobes. As with a conventional radar, the transmitter uses a large Travelling Wave Tube (TWT) microwave amplifier (usually dual redundant in the E-3) which pumps the very powerful microwave signal into the antenna. In the opposite direction, the slots/waveguides/delay elements feed into a redundant receiver which then in turn feeds a conventional pulse Doppler signal processing chain. The antenna scans in azimuth by the whole antenna assembly being rotated upon its pedestal at 6 RPM, through 360 degrees.    Both the E-2C and the E-3 integrate a primary and secondary radar capability, the secondary/IFF antennas are mounted back to back with the primary radar antenna.[URL unfurl="true"]http://www.ausairpower.net/aew-aesa.html[/URL]<h2>AN/APY-1/2 AWACS radar</h2>The primary radar housed in the rotodome is the Northrop Grumman AN/APY-1/2 AWACS <a href="https://www.airforce-technology.com/features/moonlight-artificial-intelligence-radars/">radar</a>. The radar transmitters, computers and display stations are housed within the fuselage.The radome scans at six revolutions a minute. When the radar is not operating the radome rotation rate is set at one revolution every four minutes. The radar is multi-mode using powerful interleaving and de-interleaving algorithms.The main operating modes are: pulse Doppler non-elevation scan (PDNES) for surveillance of airborne targets; pulse Doppler elevation scan (PDES) to determine the target elevation; beyond the horizon pulse radar mode; receive only mode for passive operation; standby mode; and maritime mode, which uses very short pulse width for the detection of surface ships.Boeing, with the electronic sensors and systems division of Northrop Grumman as subcontractor, carried out an E-3 AWACS RSIP, which upgrades the capability of the AN/APY-1/2 against threats from small radar cross section targets, cruise missiles and electronic countermeasures.The improvement in sensitivity against small and stealthy targets is achieved through the installation of a new surveillance radar computer (SRC) to replace the digital Doppler processor and radar correlator, and the translation of the associated software into ADA language. RSIP installation was completed on the Nato (17) and UK (seven) aircraft in 2000, on France (four) in 2006 and on the 33 USAF E-3 AWACS in April 2005.The AN/APX-103 interrogator, supplied by the Telephonics Corporation, provides both civil and military identification friend or foe (IFF) operation and instantaneously provides a data set on all targets within the radar range. The data includes IFF status, range, azimuth and elevation position and code identification. Telephonics won a contract in March 2019 to build AN/UPX-40 next-generation IFF interrogators for Saudi E-3 Sentry aircraft.[URL unfurl="true"]https://www.airforce-technology.com/projects/e3awacs/[/URL]De parte de Deagel:[URL unfurl="true"]https://www.deagel.com/Sensor%20Systems/ANAPY-2/a001208[/URL]<h3>AN/APY-2</h3><img src="https://www.deagel.com/library/md/2011/m02011062600058.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Group: Radar SystemsStatus: ActiveDerived from AN/APY-1Origin: <img src="https://www.deagel.com/assets/img/flags/c0001.png" alt="" class="fr-fic fr-dii fr-draggable " style="" />Contractor/s: Northrop GrummanNorthrop Grumman AN/APY-2 is a development of APY-1 pulse Doppler radar system installed on E-3 AWACS aircraft.  It features the ability to detect and track targets over the horizon, sea surface and/or flying at low altitude. The AN/APY-2 advanced radar system was provided to the E-3 and E-767 aircraft and features greater tracking capacity for more than 600 targets flying at low altitude. Like the APY-1, the APY-2 is mounted in the rotodome above the rear fuselage.<table style='width: 100%'><tr><td>Max Detection Range (kilometer)</td><td>520</td></tr><tr><td>Max Detection Range Against Low Altitude Threat (kilometer)</td><td>375</td></tr><tr><td>Max Instrumented Range (kilometer)</td><td>650</td></tr><tr><td>Max Surface Detection Range (kilometer)</td><td>320</td></tr><tr><td>Small Air Target Detection Range (kilometer)</td><td>400</td></tr><tr><td>Tracked Aerial Targets</td><td>600</td></tr></table></blockquote>
