The size of a target's image on radar is measured by the radar cross section or RCS, often represented by the symbol σ and expressed in square meters. This does not equal geometric area. A perfectly conducting sphere of projected cross sectional area 1 m 2 (i.e. a diameter of 1.13 m) will have an RCS of 1 m 2. For radar wavelengths much less ...
The Zhuk has a weight of 250 kg and uses a 680 mm electronically scanned slotted planar array antenna which offers a detection range of 90 km against a target with a 5 m 2 radar cross-section (RCS). The radar can track 10–12 targets while engaging 2–4 of them with a scanning area of +/- 90 degrees in azimuth and +55/-40 degrees in elevation ...
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 ]
In a radar image, one can see only the energy that was reflected back towards the radar antenna. The radar moves along a flight path and the area illuminated by the radar, or footprint, is moved along the surface in a swath, building the image as it does so. [1] Digital radar images are composed of many dots.
Vertical cross-section through a supercell showing the BWER. The bounded weak echo region, also known as a BWER or a vault, is a radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which extends upward into, and is surrounded by higher reflectivities aloft, forming a kind of dome of weak echoes.
The detection performance of the Zaslon radar is stated to be 200 km against a target with a radar cross section (RCS) of 16 m 2, the radar can track up to 10 targets while engaging 4 of those at any one time with either R-33 radar guided or R-40, R-60 IR-guided air-to-air missiles. [5] The Zaslon was the Soviet Union's second look-down/shoot ...
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
An object that has multiple reflections from smooth surfaces produces a radar return of greater magnitude than might be expected from the physical size of the object. This effect was put to use on the ADM-20 Quail, a small decoy missile which had the same radar cross section as a B-52.
