Abstract
Typically, the detection of an object of interest improves as we view the object from multiple angles. For cases where viewing angle matters, object detection can be improved further, by optimally selecting the viewing angles. This motivates the search for viewing angles that maximize the expected probability of detection. In our work, we address the selection of object viewing angle for subsea sensing in which sonar is used for bathymetric imaging. For a fixed viewing distance to a symmetric object of interest, our goal is to select viewing angles that maximize the expected probability of detection. We rigorously show that when an object of interest is viewed twice from a fixed distance, the expected probability of detection is maximized for orthogonal viewing angles.
