Target angle submarine observer estimating target angle pictures himself on the target ship looking back at the submarine. Relative bearing of the submarine is the clockwise angle in degrees from the heading of the target ship to a straight line drawn from the target ship to the submarine. When target angle is 0° (or 360° ) the target ship is coming directly toward the submarine. Target angles between 0° and 90° indicate the target ship is moving toward and to the right of the submarine. Target angles between 90° and 180° indicate the target ship is moving to the right and away
Right-angle weave Right-angle weave Right-Angle weave stitch, also known as RAW, is an off-loom bead weaving technique. Beads are stitched together with thread only making right angle turns, hence the name. The result is an almost fabric like piece of beadwork. Right-Angle weave can be woven with either one needle or two. With single needle right-angle weave, the thread path moves in a figure-eight pattern. For double needle right-angle weave, the threads cross each other along the center bead of each stitch as they head in opposite directions. RAW can be formed into flat pieces, tubes, or 3 dimensional figures. There are
