摘要： Impact discriminating apparatus for missiles and the like comprises a plurality of impact sensors disposed in spaced relationship along the longitudinal axis, and near the nose, of the missile. Sensors, responsive to elastic domain impact stress or shock waves, are separately fed into pulse generators wherein output pulses of different widths are formed for each sensor, overlapping pulses associated with all the sensors being generated for rearwardly propagated shock waves caused by a direct hit, but not for forwardly propagated shock waves caused, for example, by a stabilizer fin striking tree branches or other non-target objects. The generated pulses are fed to a NAND gate which is activated to cause fusing or detonation of the missile only by the overlapping pulses respresentative of a direct hit. Blanking circuitry blanks out effects of rearwardly propagated shock waves which are merely reflections of forwardly propagated shock waves, in order to prevent unintentional fusing or detonation. Pulse height discrimination is also provided to prevent unintentional fusing or detonation by low impact direct contact with such objects as foliage or raindrops or by low impact, glancing hits against tree branches and the like. A corresponding impact discrimination method is provided.
