Conversely, a square flat plate of area 1 m 2 will have an RCS of σ = 4π A 2 / λ 2 (where A=area, λ=wavelength), or 139.62 m 2 at 1 GHz if the radar is perpendicular to the flat surface. [2] At off-normal incident angles , energy is reflected away from the receiver, reducing the RCS.
The scale of dBZ values can be seen along the bottom of the image. Decibel relative to Z, or dBZ, is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

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 ...
Somehow the current article misses a major usage by radar and ECM designers & analysts: the use of dBsm (which has no article at present) to express the measured RCS. There's one implied calculation in the RCS article when it mentions reducing detection range by shrinking the RCS, but the actual math is omitted.
A radar with a 1° horizontal beamwidth that sweeps the entire 360° horizon every 2 seconds with a PRF of 1080 Hz will radiate 6 pulses over each 1-degree arc. If the receiver needs at least 12 reflected pulses of similar amplitudes to achieve an acceptable probability of detection, then there are three choices for the designer: double the PRF ...
RAD 480i. For those looking for low-cost but suitable protection from police radar, the Cobra RAD 480i provides the basics, including detection of all radar bands and laser signals.
The Nebo-M [1] or Nebo-ME (in Cyrillic: 55Ж6МЕ «Небо-МЕ», Nebo means "sky") also known as RLM-ME or 55Zh6ME (export version) [2] is an integrated multi-functional radar system that features a multiple programmable multi-band design radars and a central data fusion. The radar began to be investigated in 1984.
