摘　　要：首先,介绍一种手持式定向强声盾牌的检测方法。区别于传统固定式强声定向设备检测方法,此方法根据手持式定向强声盾牌的特点增加了背面峰值声压级和垂直方向波束宽度的检测。其次,根据此方法基于模拟机械手臂研制一套全自动检测装置。最后,使用此装置检测手持式定向强声盾牌。测试结果表明,通过此方法和装置可描述手持式定向强声盾牌产生的声场,评估其对远端目标和操作者位置的影响。Firstly,a test method of hand-held directional high-intensity shield is introduced,which is different from the test methods of traditional stationary high-intensity directional devices.The peak sound pressure level on the back and horizontal beam angle are added in this test method.Secondly,according to this method,an automatic test device is developed using a simulated robotic arm.Finally,an hand-held directional high-intensity shield is tested using this device.The test results show that this method and divice can be used to describe the sound field produced by hand-held directional high-intensity shield,and the impact on remote targets and the operator position can be evaluated.
