Well, I kind of go through the pics, scan for what is prepared there. Sometimes I find what others have found before me, and other times I find something new.
A basic assumption is that Alpha areas for air defence are preplanned dug in positions revetments for mobile SAM's. You also have fixed sites. I guess I have mapped up most of North Korea, but I've just started on Iran.
You can start with turning on military layers in Google Earth.
In Korea you will find an area SAM covering a large area. Then two SAM's covering the airbase (SA-3) and a lot of revetments for radar controlled and barrage AAA.
In Iran they tend to do it similar, with less AAA and more mobile stuff. The reason for this is that revetments and fixed SAM-sites are so easily ID'd. The Iranians have learned.
You can ID the different site's by the radar or concrete pad patterns.
If you take a look at Bushehr AB, you'll find two fixed Hawk-sites and one SA-5 site. SOC has tracked down most SA-5 and SA-2 sites, and he's good at it.

For Iran the easy thing to spot a site is to look for a large fenced area containing roads and concrete pads. The engagement zone will not be obstructed by tall buildings, hills or mountains.
At Busher you'll also find sites not posted on Google. They are prepared sites for mobilization of more SAM's.
If you ask yourself; Where would I put the SAM's, what types and how many do I need ? .... you'll find them.
Bushehr is a nest of SAM's. I would expect a wartime SAM number of 4 Hawks or similar, At least one of the new mobile bad ass units, several of the other mobile types, radar and IR + AAA.
Busher is so tactically important that it basicly would be a nogo area for any hostile plane. Assets to target guided weapons like JDAM's, JSOW's Tomahawks etc would be available and operating very smart with deception tactics, and of course datalinked.
