But radar is much different than passively receiving known radio signals that penetrate the atmosphere from above. Conceivably one could have hundreds of small receivers, scattered around within the range of one WX radar. Much less cost than the radar, and no emissions so no need to license it. I don't know if it matters but they measure transmission, not scattering and reflectivity, and they look at the droplets from below, not the side. With the proliferation of personal weather stations, it seems like another source of information that could be exploited cheaply.
