Subs that can hear a seal fart.
And now they say military radar can not tell altitude and size of a object?
HA ! what a joke.
Is Owannabomma running the show?
Or just what is the cover up?
Do they just want to follow the seed to the bad fruit B4 doing anything so the whole tree can be disposed of??

The "listening buoys" are only in important areas worth protecting.
Radar use electromagnetic radiation(light) and looks for reflections back. Radar can only accurately track altitude and size out to the horizon unless considerable energy is employed so that signal strength can remain even through the ground.
Long distance radar relies on using modulating wavelengths tuned to bounce of the ionsphere. The accuracy of such a system is greatly reduced as it is dependent on calculating the reflections the return signal followed both out bound and in bound - given the changing nature of the sky, it has difficulty being accurate as a slight exageration its like trying to see your reflection in the surface of white water rapids.
The ocean is very reflective to radar, so use of these systems over the ocean adds an extra degree of difficulty. In fact - a perfectly stealth craft from above would be plain as day over an ocean to a look down radar as it would appear as a large "hole" in the ocean's reflection.
