When we are talking about sonar performance vs the angle, I have somewhat related question: I'm very curious if the TA is equally sensitive in all directions ? I would think that no, it's most sensitive in direction perpendicular to the line (so to the sides), but wonder how big is the difference ? And what with targets directly behind, with TW pointing at them - would they be detected ? And if yes, then with the same sensivity as targets on the sides, or maybe much lower ? Is TW coverage nearly 360deg (without ownship sector) like in SC/DW or is it best to the sides, medicore on other angles and worse at 180deg (behind) ? So to listen to given direction in real life would be the boat positioned 90deg off to have best possible performance from TA ?
