HPMB倾斜攻击计算机设备的毁伤能力分析

为了研究高功率微波弹(HPMB)攻击倾角对目标毁伤能力的影响,给出了HPMB毁伤区域的威力椭圆模型。结合高功率微波损坏和干扰电子元器件的能量阈值,提出了威力椭圆失效区、干扰区及安全区的概念,并建立了相应的数学模型,得到了一种能够体现HPMB毁伤效果的毁伤区域模型。通过示例分析,得到了HPMB以不同攻击倾角起爆攻击时威力椭圆内的毁伤区域情况。分析表明:HPMB攻击电子设备时威力椭圆内的毁伤区域模型根据攻击倾角的大小分为仅有失效区存在、失效区和干扰区均存在、仅有干扰区存在、干扰区和安全区均存在4种情况;失效区边界圆的大小取决于爆炸高度,与攻击倾角无关。

Damage probability analysis of high power microwave bomb attacking computer device by oblique attitude

In order to discuss the attack dip angle impact on damage effect of high power microwave bomb (HPMB) on targets, the damage ellipse model of HPMB was presented. Combined with the energy threshold of high power microwave(HPM) damaging and perturbing electronic components, the concepts of failure area, interference area and safe area of HPMB damage ellipse were proposed. Their mathematical models were also established, and a damage range model which can reflect the HPMB damage effect was obtained. Finally, the damage range situation in damage ellipse of HPMB to targets at different attack dip angles was obtained from a realistic example analysis. The main conclusions are as follows: (1) The damage range model in damage ellipse is divided into four cases according to attack dip angle while HPMB attacking the electronic equipments. First, only failure area exists, with no interference area and safe area. Second,failure area and interference area both exist, with no safe area.Third, only interference area exists, with no failure area and safe area.Fourth,interference area and safe area both exist, with no failure area. (2) Failure area boundary circle size is determined by burst height, not the attack dip angle.
