ShouldnÂ´t Active Sonar provide target depth?

No, it shouldn't. LF/MF search and attack sonars only provide range information, although it's possible to roughly estimate depth based on conditions and intel. You can calculate depth if you get a Lloyd's Mirror effect on a lofargram, but that's not active sonar.

Depth isn't a particularly important reading because a sub is only going to be in a narrow depth slice, of like what, 0-1500 feet? You can then narrow that down based on what you know of the threat, bathythermographic conditions, sonar performance, and et cetera. It's not like an airplane which can be 1-60,000+ feet.
