The LOD problem is much more complicated for city, because you hit the
"generalization" problem.
To simplify : there is currently no satisfactory automated way to generate
complex 3D or 2D geographic information in multiple level of details.
It is actively researched.

At least preliminarily, I can post-process, so speed of db adds isn't too
troubling. Maintaining accurate representation of the bin-volume data is,
however, important.

If your radar return is well discretized in time (I'd say max 10^6
points/sec),
pointcloud could do the trick (you can have any number of attributes per
point).
Else, you would have to cut the data into pieces.

I'm glad this might work out for you.
I'm not familiar with the products you guys generate or store, but you can
even store rasters with more then one band, keeping all the data in a
single place, but different bands.

Raster is always a possibility, but we lose some data therein. If I use
what we refer to as "Level III" data, then it's certainly a potential. I'm
sorta thinking of using Level II data which comprise
azimuth/range/elevation and one of: reflectivity, radial velocity or
spectrum width (standard devia

I asked this years
If you transform it to rasters PostGIS Raster can handle them already.
Now, about the new datatype, I'll let the experts discuss :P.

(:-), but:
Has anyone, in the ensuing years looked at encoding radar data into a
postGIS database? We've a little idea that might benefit one project, and
getting the radar data into a good geospatial format would be
beneficial
