SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR). The distance the SAR device travels over a target during the period when the target scene is illuminated creates the large synthetic antenna aperture (the size of the antenna ...
The iPhone 7 and iPhone 7 Plus [a] are smartphones that were developed and marketed by Apple Inc. They are the tenth generation of the iPhone.They were announced on September 7, 2016, at the Bill Graham Civic Auditorium in San Francisco by Apple CEO Tim Cook, and were released on September 16, 2016, succeeding the iPhone 6, iPhone 6 Plus, iPhone 6S and iPhone 6S Plus as the flagship devices in ...
Inverse synthetic-aperture radar (ISAR) is a radar technique using radar imaging to generate a two-dimensional high resolution image of a target. It is analogous to conventional SAR, except that ISAR technology uses the movement of the target rather than the emitter to create the synthetic aperture. [1]
The staggered-SAR [16] can overcome this drawback by continuously varying the PRI in a cyclic manner, therefore allowing the imaging of a wide continuous swath without the need for a long antenna with multiple apertures. This works because in satellite SAR imaging, antenna length and required azimuth resolution set an upper bound to the ...
The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

Che Diaz’s time is up: Sara Ramírez is leaving the cast of Max’s And Just Like That… and won’t return for the upcoming Season 3, our sister site Variety reports.
[7] Area coverage with a traditional side-scan sonar depends on range and at what range the resolution gets too low for the target goal of the scan. Area coverage with a synthetic-aperture sonar, with an across-track resolution that is constant all the way until the end of the range, is practically closer to the instantaneous area coverage.
