P-8 radar
Encyclopedia
The "Pegmantit 8" or P-8 (also referred to by the NATO reporting name
"Knife Rest A"in the west) was an early 2D VHF radar
developed and operated by the former Soviet Union
.
, the P-3 radar
. The radar was developed and successfully tested between 1949 and 1950, demonstrating a detection range of 150 km against a target aircraft at 8 km altitude and was accepted into operational service. The P-8 was developed by the SKB Design Bureau, a division of State Plant No.197 named after V.I.Lenin who developed the previous P-3, the predecessor of the current Nizhniy Novgorod Research Institute of Radio Engineering (NNIIRT). The development of the P-8 radar won the team responsible for its introduction the state prize.
In 1951 the P-8 radar underwent a significant modification which boosted the detecton range to 250 km against a target flying at an altitude of 10 km, the target detection range of low altitude targets was also improved by a factor of 60-70%. Between 1956 and 1957 the P-10 and legacy P-8 radar were equipped with improved clutter suppression equipment allowing for cancellation of clutter moving up to 30 m/sec, cancellation was improved by a factor of 5 compared with no cancellation.
trucks. The P-8 used a single antenna
accomplishing both transmission
and reception which rotated at a speed of 2 r.p.m. The antenna was composed of four Yagi antenna
s mounted in sets of two with one set above the other atop a 30 meter mast. Azimuth was scanned mechanically by the antenna with elevation determined using a Goniometer
in similar fashion to the P-3. The P-8 was one of the first Russian radars to incorporate a means of clutter
suppression, a coherent oscillator in the receiver circuit acted as a simple moving target indicator to eliminate passive interference like ground clutter. The P-8 was also the first Russian radar to use a plan position indicator in addition to an A-scope to indicate height, the radar had a maximum power output of up to 75 kW and a receiver sensitivity of 7 mV.

Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry is derived from two Greek words, gōnia, meaning angle, and metron, meaning measure....

Clutter (radar)
Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems.- Backscatter coefficient...

Operators
The P-8 was operated by the Soviet Union from 1950 but has long since become obsolete and retired from service, replaced by more advanced models entering into service after the P-8 such as the P-10 radarP-10 radar
