Again, this particular DIY radar has no application in Ukraine. It does not have a 50+km range (10km). It can not direct or interface with an interceptor missile, of any kind, to shoot down TBMs, Shaheds, etc. The critical issue really is how many interceptor missiles Ukraine has and far less about janky early-warning radar coverage.
Acoustics are used for FPVs, which have a tiny radar cross section and can fly at tree top altitude or lower. A basic/crude DIY radar would not be effective there and at $12,000 vs $Free, acoustics win hands down for FPVs. The Gepards (AA gun) have their own onboard radar already for cruise missiles/shaheds. No one is proposing or expecting acoustics to track missiles or bombs. These are two very different problems.
The Russian Navy stays way, way the hell away from the Ukraine coast these days. The drone-boat bombs have them running scared. Even Sevastopol in Crimea is too risky.
