The Target Identification And Distinguish Technology Of The Lazer Proximity Fuse

The laser proximity fuze is part of precision strike weapons.It is one of the important signs of the new generation of guided weapons. Since the technology of laser proximity fuze appeared, because of its good directionality, high monochromaticity, coherence, it has been more and more widely used in modern warfare.The hit rate of the tactical/strategic missiles, rockets, artillery, anti tank weapons can be significantly improved effectly.The laser proximity fuze anti electromagnetic interference ability is prominent, but there are some defects in the anti interference ability, especially the sunshine, rain and snow, fog and so on.They are caused by the defect of the theory. If there is not any inappropriate remedy, they could cause false alarm, causing the weapon early burst, lossing the ability of destroying target.Combining theory with practice, the article summarizes the author’s learning knowledge and experience in the actual practice of scientific research. At the beginning, the article introduces the laser proximity fuze target detection principle and common detection system, and then analyzes the objective existent jamming source of the laser proximity fuze in the battlefield, and then puts forward the method of how to fight against these interference, eliminate or reduce the harm they bring on. Then a laser proximity fuze is developed as an example, the design of the components and the matters needing attention are introduced, especially the work of anti interference. The construction of the test environment and test methods and then describe the actual proof that interference design can effectively resist sunlight, rain and snow and clouds. Finally, a summary of the whole article and proposes further research problems.
