New blog post: Analysis of the CAMRAS Venus radar experiment. A deep dive into the Earth-Venus-Earth L-band radar experiment done in March by @radiotelescoop, Astropeiler Stockert, the Deep Space Exploration Society, and @OpenResearchIns.

I show how to compute the radar Doppler with SPICE and come up with a Doppler spread model based on an S-band scattering model from Arecibo. I explain why the maximum surface Doppler offset is 8.6 Hz even though the rotational velocity predicts 15.7 Hz.

@destevez @radiotelescoop @OpenResearchIns Very cool!

My summary: International collaboration of amateur radio astronomers, at multiple sites, with heritage dishes still in service, bounce radar signals off Venus. They measure the doppler shift, of the reflections from the surface, due to the planet's rotation.
