Research On Directional Technology And Injury Assessment Technology Of Sonic Non-lethal Weapons

Acoustic non-lethal weapon is a new concept weapon.It can emit strong sound to a specific target and then achieve an effective attack on the target.Therefore,the key technology of this non-lethal weapon lies in the realization of acoustic orientation system.With the change of battlefield situation,it is more and more important to clarify the value of acoustic non-lethal weapons.Therefore,more and more attention has been paid to the reasonable and effective effectiveness evaluation of acoustic non-lethal weapons.In order to better explore the directional technology and damage assessment technology of acoustic non-lethal weapons,this paper mainly studies the directional technology of acoustic non-lethal weapons and the damage effectiveness assessment technology of acoustic non-lethal weapons.Based on its basic theory,the following work is done:(1)The overall framework of the hardware principle of the acoustic orientation system is constructed.Because the key technology of acoustic non-lethal weapon is acoustic orientation system,this paper constructs the overall framework of hardware principle of acoustic orientation system based on theoretical analysis,and establishes signal generation module,signal processing module,power amplification module and ultrasonic transducer module,and completes the design of system hardware principle prototype based on the above modules.Finally,the acoustic directivity of the prototype of the acoustic directional system designed in this paper is verified,and the results show that the prototype has good directivity,and that the design scheme in this paper has the rationality.(2)The evaluation of the lethal effectiveness of typical single-item effectiveness of acoustic non-lethal weapons is achieved.In this paper,a damage assessment system is established based on the analysis of the damage process of non-lethal acoustic weapons.Then,an injury assessment model is built based on the analytic hierarchy process(AHP)and the fuzzy control theory,and a damage probability assessment model is established based on the analytic hierarchy process(AHP)and Bayesian network(BN).Finally,this paper validates the established acoustic injury effectiveness model,and evaluates the injury effect of guinea pigs from two aspects of experiment and model calculation.The experimental results are basically consistent with the model evaluation results,which proves the rationality of the established injury effectiveness model.
