In order to study the dispensing parameters of the airborne chaff cartridges,the mathematical models of the interval,the numbers dispensed,and the damage reduction factor of the aircraft are respectively created.Based on the principles of using the airborne chaff cartridges to interfere with radars,the dispensing interval and numbers of the chaff cartridges are modeled and simulated with the successful centroid jamming as restriction.According to such specific simulation conditions as the radar wavelength,aircraft speed and attack angles of missiles,the dispensing parameters that satisfy the centroid jamming are obtained,on the basis of which the dispensing parameters that make the damage reduction factor of the aircraft bigger are optimum ones.%为了研究机载箔条弹的投放参数问题,分别建立了箔条弹间隔、弹数、飞机损伤降低系数的数学模型。在机载箔条弹干扰雷达原理的基础上,主要以质心干扰成功作为约束,对机载箔条弹的投放间隔和弹数进行建模仿真。根据雷达波长、飞机速度、导弹攻击角等具体的仿真条件得到满足质心干扰的干扰投放参数,在此基础上选择使飞机损伤降低系数更大的箔条弹干扰投放参数为最佳投放参数。
