Multi-receiver complex interferometers.
Even a spread-spectrum radar is a hot radiator if you're
building a broadband, 2D or 3D complex passive map (though
you do have to calculate out the time delays as well as the
phase shifts). Of course, it requires tight timing
synchronization, but they've been doing that with
radiotelescopes for years--though there they record
the data and post-calculate instead of doing it in real-time.
 
You can do it with stationary or moving receivers.
The more receivers, the better. For a small to moderate
area of interest, you could use numerous drones, for example.
