Considerations for bistatic probing of clear-air winds in the atmospheric boundary layer

Bistatic radar measurement of clear‐air winds in the atmospheric boundary layer is considered. The context is three‐dimensional wind field measurement using dense networks of short‐range radars configured to operate in bistatic geometries. Such networks exploit a combination of Rayleigh scattering from insects and Bragg scattering from refractive index turbulence, the latter exhibiting enhanced scattering intensity in forward scatter geometries compared to the monostatic case. Bistatic radar fundamentals are reviewed, and beam‐limited scattering volumes are considered. Measurements with sufficient precision (
