Target angle is the relative bearing of the observing station from the vehicle being observed. It may be used to compute point-of-aim for a fire-control problem when vehicle range and speed can be estimated from other information. Target angle may be best explained from the example of a submarine preparing to launch a straight-run (non-homing) torpedo at a moving … Web(Some x-ray tubes are cooled with water.) The target is cut on a diagonal so that the emitted x-rays fly off the surface at an angle different from the incident electrons. A 45° cut makes the x-rays exit perpendicular to the axis of the tube. All the photographs of x-ray tubes on this page have their targets aligned at this angle.
