A method and a device for testing optronic weapon systems are to be designed for being able to reproducibly also take into consideration in the test process the effects of different dynamic situations in the beam path (20) in optronic amplitude or triangulation-type proximity fuses (3), which situations correspond to different transmission conditions and different approach speeds of the fuse (3) to a target object reflecting radiation energy. For this purpose, the receiver (5) is excited by means of a test device (10) from a stable radiation source (11), which is preferably the fuse transmitter (4) itself, via an interposed attenuation section (14); the attenuation values (22) becoming successively effective being read out of a memory (24) at variable address incrementing rate. The digitally stored attenuation values (22) correspond to signal variations (1, 2), which can be determined in a steady-state manner, in the receiver circuit (7) for different energy transmission situations in the beam path (20) between transmitter (4) and receiver (5) of the optronic proximity fuse (3). However, such signal variations (1, 2) can also be obtained by means of telemetry measures when firing trial munitions and entered into the memory (23) as sequences of attenuation values (22) to be read out, after digitisation. <IMAGE> |
