OVERVIEW:  The SA-4a GANEF (2K11, 3M8M1) battery is a mobile, air defense unit intended to protect combat formations against medium-to-high level air threats at medium range.

DETAILS:  

A typical engagment begins with the initial target detection P-40 "Long Track" early warning E-band radar, which has a 150 km range and 30 km maximum altitude coverage. Target data is then passed to the SA-4 `Ganef' battery where the 1S32 H-band `Pat Hand' continuous wave fire control and command guidance radar takes over. This radar typically acquires the target at about 120 to 130 km and, when it is within 80 to 90 km, tracking can begin. The PRV-9 "Thin Skin" truck or trailer-mounted height-finder radar also provides height information. If required, the `Pat Hand' can handle two missiles per target in order to increase kill probability. Optical tracking is possible for guidance in a heavy ECM environment.
