А что такое СПО?
СПО -
станция
предупреждения об
облучении - радиотехническое устройство, предназначенное для регистрации облучения самолета радиолокационными станциями противника и предупреждения об этом экипажа. Например:

http://www.overscan.co.uk/Avionics_files/SPO-15l.jpg [not image] http://www.overscan.co.uk/Avionics_files/spo-15b.jpg [not image]Hybrid analogue/digital radar warning receiver. Sucessor to the Sirena-3M. Specifications were agreed upon in 1969, project was launched in 1970. Entered service in the late 70s.
SPO-15 is comprised of the following components:
forward azimuth antennae
control centre
cockpit indicator station
HF converters
reciever
computer
elevation angle antennae
Power supply
Long range antennae
The Su-24 system has full 360° coverage while all other aircraft have a simpler system with full coverage in the front 180° and simple "left or right" detection in the rear sector.
The outer yellow lights represent the azimuth angle of the most threatening target. The light will remain lit for 8-12 seconds, so a scan rate less than this will result in a permanently lit light. The inner green dots show all other targets. The lights will indicate the approximate direction. If the emitter lies in a direction between two lights both adjacent lights will light up. The six lights across the bottom represents 6 target types which will show the radar type of the most threatening target. The inner ring of yellow indicators light up successively to show the strength of the received signal. As well as the visual indicator, a low pitched sound with similar characteristics to the detected radar signal will be given.
If the hostile radar switches to tracking (STT) the red circle will flash and a continuous high pitched audio tone will sound.
When a SAM launch is detected a continuous variable pitch sound will be given.
The Beryoza is claimed to be capable of detecting enemy airborne radars at 120% of the distance within which the enemy fighter can launch a missile.
Radars operating in TWS mode cannot be distinguished from search mode.
The priority target is simply detirmined by target type- one type is always considered more dangerous than another, regardless of signal strength or other factors.
