由于推进剂、炸药,战斗部和弹丸的设计,发射以及弹上制导和控制技术的进展,使低空防御所使用的火炮和导弹的性能得到稳定地改进。但是,最引人注目的改进是由于采用现代微电子设备而经常获得成功。这可将如此多的计算能力组装在小的体积内,甚至在轻型防空武器具有相当低的价格,强大的数据处理能用于雷达和激光信号,电视和热像仪产生的图象,以及有效的指挥,控制和通讯所需要的数据。现在为新的近程防空系统提供了包括这些技术进展,现有的设备,使它能得到改善,并使它进一步延长寿命。本文研究许多领域内的典型的进展情况,但不打算列举每一种单个的设备。 Advances in the design and launch of propellants, explosives, warheads and projectiles, as well as guidance and control technology on missiles, resulted in a steady improvement in the performance of artillery and missiles used in low-level defense. However, the most noticeable improvement is the often successful use of modern microelectronic devices. This can pack so much computing power in a small volume, even at light-weight air defense, at a reasonably low price that powerful data processing can be used for radar and laser signals, images generated by television and thermal imagers, and effective The command, control and communications required data. The new short-range air defense systems are now included to include these advances in technology, existing equipment, so that it can be improved, and make it to further extend the life expectancy. This article examines the typical developments in many areas, but does not intend to list every single device.
