Stupid questions about ... what I have read and studied.

My english is lacking to explain you what a frequency is.... eh.. high pitched noises are high frequency and low pitched noises are low frequency. For instance the ships/subs electrical system is 60 (USA) or 50 (Russia and otres) Hertz, which is low frequency... and that is best detectable by the towed array.

For the gameplay, each platform, when you look at it in NarrowBand station, emits i think 5 (it can be less, depends on the sensor used, distance etc.) distinct frequencies - they are depicted as lines. Now u use the database to list known platforms and their sonar profiles, and if you see the lines from database to match those you get from NB sonar, you have likely identified the target

That is, because when you assign a sonar tracker, it gives you only target's bearing, NOT range.... you have to use TMA to get target's range. But doing TMA is not actually easy, after years of playing subsims i learned it relatively good, but it is matter of time
