The vast majority of SAR satellites are below 500W and have a beam "footprint" of about 5km by 5km at minimum.
Imagine 5 100W lightbulbs reflected and focused to channel as much light as possible onto a 25 square kilometer field from hundreds of kilometers away.
The planes are fine.
- m2fkxy 2y agoyes, received power is inversely proportional to the distance squared. it's hard to overstate how ridiculously small the amounts of power are at play with spaceborne SAR systems.
