国外高炮射击指挥系统近期发展的特点及其趋势是与“低空防御”这个问题密切相关的。为此,首先谈谈“低空防御”及其对防空武器系统提出一些基本要求。大家知道,美帝国主义和苏修社会帝国主义,为争夺世界霸权和镇压各国人民革命,常常采取突然袭击的方式发动侵略战争。他们都特别强调对地面攻击的飞机,应具有高空高速突防和低空、超低空、亚音速突防的能力。在现在技术条件下,由于雷达技术的发展和防空导弹的广泛应用,国外一般认为,高空或中空突防是代价大而难以成功的,然而由于雷达存在盲区及武器不易跟踪和瞄准,为低空、超低空突防提供了机会。因此,美帝、苏修近年来 The characteristics and trends of the recent developments in the firing command system of foreign artillery guns are closely linked to the issue of “low-altitude defense.” To that end, let us first talk about “low-level defense” and its basic requirements for air defense weapon systems. As we all know, the US imperialists and the Soviet revisionist social-imperialists often launched a war of aggression in the form of a surprise attack to fight for world hegemony and suppress the revolutions of the peoples of various countries. They all emphasized the ground attack aircraft, should have high-altitude high-speed penetration and low-altitude, low altitude, subsonic penetration ability. Under the current technical conditions, due to the development of radar technology and the wide application of air defense missiles, it is generally believed that the penetration at high altitude or in the hollow is costly and difficult to succeed. However, due to the blind spot in the radar and the difficulty of tracking and aiming the weapons, Ultra-low-level penetration provides an opportunity. Therefore, the US imperialism and Soviet revisionism in recent years
