Abstract: In order to measure the jamming effect of smoke on laser guided weapon, an interference effect semi-physical simulation measurement system is established. The evaluation rules of jamming effectiveness are presented according to the connotation of the test and evaluation of smoke jamming, and the smoke jamming evaluation method is discussed. It is determined whether a jamming is effective or not according to the changing of the tracking error, guidance accuracy of electro-optical guidance system or hit probability. The test result of the smoke screen jamming laser guided weapons under typical weather environment and different bomb release modes are given. Experimental results show that the jamming effectiveness changes with smoke transmissivity.

Key words: ordnance science and technology, smoke screen interference, laser guidance, jamming effect, semi-physical simulation
