Our global intel ability is about to take a great leap forward. ............ SAR has been around for a long time with an aircraft platform, but now will be space based with photo quality resolution. ............. Our enemies have learned to move and operate at night and under clouds to avoid our satellites. ............. SAR can now see them 24/7, anywhere, night or day, rain or shine, in 3D. ............. SAR carried by aircraft or drones is of very limited use only while airborne. ............... SAR satellites can permanently deploy antenna thousands of meters long, and cover the entire Earth. Shipping, weapons and drug smuggling, subs surfacing at night, troop movements, anything. Photo'd in real time in 3D.

The antenna CAN be physically long, but doesn’t have to be. The ‘synthetic’ aspect of the aperture, like creating a ‘huge’ lens on a telescope, is due the the speed of the satellite over the surface of the earth.
When the RADAR beam leaves the satellite, the satellite is over position A, when the return comes back, the satellite has moved XXX meters, and the software transforms that into what is essentially a VERY large lens — using RADAR frequency instead of visible light for the image.
I forget the name of the aircraft that did this in the Gulf war, but they also used a poor man’s tool - VCR on fast forward — to look at the RADAR tapes and see where Saddam’s truck yards were and other marshaling areas. I do recall the aircraft looking rather ungainly with a large angular ‘pod’ along the bottom of the fuselage.

sub 0.5 meter res is hardly space based photo quality; they could count head hairs in the 60s and newer ones can tell the color of your eyes at night with overcast and rain

I’ll sleep better knowing that the government can carefully track all those evil serfs who do not obey stay-at-home orders...

JSTARS!
Joint Surveillance Target Attack Radar System, or JSTARS. The aircraft used Ground Moving Target Indicator and Synthetic Aperture Radar, or SAR.
The E8-C
