Determining the miss distance when firing at practice targets

摘要

A chain of pressure sensors 2 is used to detect the pressure wave 7 of a missile 6 aimed at a target, e.g. associated with sensor 5; the sensors 2 emit staggered pulses which are evaluated in a computer to determine the miss distance and the angle of the missile trajectory relative to the sensor chain. A separate sensor is used to determine temperature and then the absolute velocity of the missile can be derived. The sensors may comprise piezoelectric devices and the target may also have further sensors 4 extending laterally of the main line of sensors.
