TA vs Spherical in BB mode.

King_Zog · 03-18-13, 04:26 AM

I've noticed that some of the time in broad band mode: my spherical array will show quiet running submarine contacts on the long and short term waterfalls long before my towed array (in BB) will pick up the same contact. (Even though the TA was first to 'see' the submarine in narrow band mode).

I thought that the towed array should always pick up quiet low frequency contacts first and at a longer ranges even in BB - like it always does in narrow band mode.

Can someone please explain why this sometimes doesn't seem to be the case on the broadband waterfalls?
