Possibly used a cassegrain antenna. Elements derived from Smerch series
radar. Search range 30km, tracking range 15km versus a 16 sq m target.
RP-22S was fitted to the MiG-21S, used in Soviet
service only from 1965 onwards.
RP-22SM was fitted to the upgraded MiG-21SM, also not
exported, and later equipped the MiG-21bis which was exported once the RP-22SM was no longer
considered "sensitive".
RP-22SMA probably RP-22SM-A (version for warpac).

Kopyo was the first private venture radar by Phazotron. Drawing on technology developed for the
Zhuk radar, Phazotron produced Kopyo as a lighter, smaller radar suitable for equipping trainers
and light attack aircraft as well as for upgrading older aircraft like the MiG-21. It uses both
high PRF and medium PRF modes for optimum detection and tracking at all aspects. Kopyo weighs
120kg, occupies 250dm3, with a 500mm antenna that achieves 29dB gain. Tracking limits of the
radar are ±40°. Kopyo has 2 recievers, and transmits with a peak power of 5kw, 1kw average. It
uses an MPS data processor, and a TS175 digital computer. Its MTBF is 120 hours.
Kopyo has an air-to-air track-while-scan ("SNP") mode, it tracks 10 targets, and engages 2
simultaneously. The simultaneous engagement capability has been demonstrated.
It retains a single target track mode. Search range is 57km headon and 25 - 30 km pursuit, with
a tracking range of 45km, against a 3 sq m RCS target. It has vertical scan, automatic HUD scan
(+- 14°), optical (pilot selected target on HUD) and helmet close combat modes.
Air-to-surface operating modes are comprehensive, something Phazotron only introduced in the
current crop of radar designs. There are three mapping modes; low resolution (real beam);
medium resolution (Doppler beam sharpening, 10:1); high resolution (synthetic aperture, 100:1).
Allows detection of moving ground targets, sea surface search, map freezing and interfaces with
the Kh-31A antiship missile for target handoff. |

Air-to-air operating mode
1. Detection range (Ddet), km:
- against free airspace:
head-on >50
in pursuit >30
- against surface background:
head-on >50
in pursuit >25
2. Single target detection and tracking range 0.75 Ddet
3. Track-while-scan with simultaneous engagement of two targets
4. Air-to-air missile targeting and launch zone generation
5. Close air combat in the following modes of radar operation
- vertical
- collimating
- visual, with the helmet-mounted target designator used
- interfacing with the helmet-mounted target designator
- interfacing with the R-27, RVV-AE and R-73E missiles
- radar built-in test
Air-to-surface operating mode:
- mapping:
low resolution (real beam)
medium resolution (Doppler sharpening beam)
high resolution (synthetic aperture)
- interfacing with the Kh-31A antiship missile
- detection of moving ground targets
