坦克以坚固的装甲抵御反坦克武器的攻击。随着反坦克武器威力的日益增强,尤其是攻击坦克顶部武器的出现,单纯依靠被动防护难以保证坦克在战场上的生存,于是坦克的主动防护系统应运而生。主动防护系统可以在一定距离干扰或拦截反坦克弹,使之不能命中目标,保护坦克的安全。根据防护机制的不同,主动防护系统分为软杀伤和硬杀伤两类。“软杀伤系统”只是使威胁战车安全的攻击弹药迷失目标,不能对它造成硬损伤;“硬杀伤系统”则是在攻击弹药到达之前就将它摧毁,或起码使其受损并大大降 Tanks with solid armor against the attack of anti-tank weapons. With the increasing power of anti-tank weapons, especially the emergence of weapons attacking the top of tanks, it is hard to guarantee the existence of tanks on the battlefield based solely on passive defense. Therefore, the active protection system of tanks came into being. Active protection system can intercept or intercept anti-tank bombs at a distance so that they can not hit the target and protect the tank’s safety. According to the different protection mechanisms, active protection system is divided into soft kill and hard kill two categories. The “soft kill system” only loses the target of an attacking ammunition that threatens the safety of a chariot vehicle and can not cause hard damage to it; a “hard kill system” destroys it, or at least impairs it and greatly reduces it before the attacking ammunition arrives
