What is that very faint sound after each sonar pulse because each pulse has 3 sounds on the graph and the last one is very short and faint but in some videos especially of divers encountering sonar while in the water is is still a short sound but definitely louder
Speed? You would have needed 2 returns to verify direction which would also give you its speed. Do you know where I might find videos or sites that show sonar and radar returns and ID charts and tutorials?
Transmitting multiple pings including one FMCW (frequency modulated continuous wave) and another CW with a relatively higher frequency. The faint fades in the tail of both FMCW and CW are the effects of reverberation (ocean is like a box so the reflection from surface and/or seabed are called reverberation that is how it differs from echo!), this tail fades away (after couple of reflection, reflecting again and again and the acoustic energy is absorbed) by time. I've observed a third signal, notably higher in frequency compared to these two. It does not have harmonics as these two FMCW and CW have harmonics (look at the frequency range between 6-7 kHz). That leads me to believe this third signal is an echo reflected from a moving object, the Doppler shift, suggesting the object is moving toward the transmitter.
I was looking for sonar and returns of different vessels and maybe a tutorial on how they are ID'd. Good video though. I thought Pings were more pronounced like a bat chirp.
Different tones and pulse lengths for different purposes. Lower frequencies are used for long-range scanning, detecting, and tracking. Higher frequencies and shorter pulses are used for detection and tracking at closer ranges. Higher frequencies are also used for bathymetry and other kinds of scanning where a higher level of detail is required, like in mapping or identifying wrecks.
Actually that particular system can reach up to 230db, which would shake your body to death if you were even 200m away from the ship. Even at a few kilometers away it can rupture a human eardrum.
+Hibblejaybob This sounds like a 53 series sonar employed on Arleigh Burke or Spruance class destroyers or possibly a Ticonderoga class cruiser. The transmission is coded pulse (CP) followed by an ODT burst. You can see the freq on the left is roughly 3.2khz for the CP part of the transmission and 3.8khz for the omni-directional part of the transmission.

Sonar tech for 14 years. I haven't heard the 53 in a while. Thanks for posting.

53 as in the model of transducer?
@@jonv.6213 yeah AN/SQS-53, pretty common on US surface ships.
Conn, sonar contact designated sierra 1, bearing 250 at 5000yds over

He's not giving the contact's bearing - he's giving the bearing of the contact relative to the vessel he's in, bearing 250 would be red 110
nice try comrade
OK That makes sense, My crew would tell me where he is going and how fast at what depth and if constant.
Don't say over on an internal circuit!

verify the range to target, give me one ping.
One ping only please
@@rldrkp7946 that’s what she said
@@AugustDH what???
@@musical_will Honestly, even I'm confused.
wow that seems to be really loud
Yes. If you were diving very near it, you would suffer total hearing loss. It's well over 240 db if it's at full power.
CoolSpace hearing loss? Ur fuckin Organs would get ripped apart
@@jms2922 still deaf when youre dead
@@coolspace2136 if you were diving very near it you would be literally human soup
If they’re using active sonar there either training or they’re looking for something.

Good video though.

Aperantly its 140 decibels as loud as a vomecial plain taking off

What was pinging the station?

The fact that you can tell that by looking at one graph and hearing three pings is impressive.
Thanks.
Just makes the targets even bigger targets
When you sleep below the waterline of a DD or a CG, you learn quickly what your sonar sounds like.
Holy moly
