What is bearing scatter ? Has it something to do with sound wave scattering and arriving to receiver from different bearings or is it something freq related ? And second (related?) question, what is angular resolution of a towed array for such low freqs (1-10Hz), can you get exact bearing of such signal - like for higher freqs, or maybe only it's general direction +/- 30 deg for example ? I'm not sure how precisely can be measured bearing of signal that has wave lenght comparable to towed array size... :hmm: Even if it arrives from the side...
