You can always mount the transmitters in trucks and keep moving. If you can pinpoint the source and fuse the input of, say, dozens of small sensors deployed all over the place, you can pinpoint the plane well enough.

Not well enough to do reliably do missile tracking, just enough to get an idea that yes, there is an object out there in the atmosphere. "Dumb" methods like TDOA / FDOA have quite bad limitations on resolution.
Multistatic passive radar is quite hard to do at high performance. Radio astronomy observatories have been doing it for decades; it's expensive, requires high grade equipment to synchronize time and frequency, and reliable, real-time high-bandwidth data links.
