註釋

Four spherical munition surrogates were constructed to span a range of densities (specific gravity between 1.8 and 7.7). Surrogates were deployed in pairs at five different locations on the beach and at three different burial depths. Each scenario was repeated five times to determine a probabilistic response to repeatable forcing, determined by sensor data comparison for all runs. The beach was reshaped manually between subsequent runs, and a root-mean-square elevation error of less than 3 mm was maintained. Imagery from the overhead camera was converted to real world coordinates through a camera calibration and rectification. Cross-shore surrogate trajectories were traced using a motion-based object tracking technique and validated through manual measurements.
