Radars are very much in use in Ukraine. There is a whole range of air targets besides FPV drones, there are ballistic missiles, fighter planes, bomber planes, helicopters, gliding bombs, and ships, all of which require a radar to detect.
Acoustic sensors have limited range. By the time it detects a missile, it’s already flew one kilometer away, and it’s too late to grab your AA gun. Gliding bombs are silent.
Radars have 50+ km range, and allow to shoot bombers and ships from beyond the border with expensive US-provided missiles.
