| I've seen a number of comments to the effect that, in the age of stealth fighters, air combat tactics will resemble submarine warfare. Looking at sonar technology, it looks as if subs have had AESA type capabilities with their sonar arrays for quite a while, but I've never really heard anything about "LPI" active sonar in the way people here talk about AESA LOI radar. Anyone know anything about this? |

| What is AESA-like about sonar? |

| Sonar is done with emission and detection arrays, just like AESA, but with sound waves instead of radio waves. Active sonar "pings" are beamed the same way AESA radar pulses are beamed. I'm not sure that the same elements that emit are always the ones that receive, but, once you get past the physical difference between sound waves and radio waves, the systems basically operate on the same principles. |
