从近来的局部战争陆基防空雷达面临的任务出发，简要阐述了近来出现的各种目标的特点以及防空雷达所处的作战环境与电子对抗环境。分析了陆基中低空防空系统在现代防空中的作用和地位。陆基中低空防空系统在现在的防空中是可以发挥它的重要作用的，尤其是在对付巡航导弹、武装直升机、低空飞机（含隐身飞机）、反辐射导弹等目标时，该系统是属于比较优选的武器；归纳了对陆基中低空防空雷达的新的要求，主要是强的抗干扰性能，好的低空特性，满足武器系统需要的探测小目标的能力，快速的搜捕截获目标的能力等；同时也简要分析了这些要求在陆基中低空防空雷达中的技术可实现性。

In light of tasks creating before ground based air defense radar in recent regional conflicts, this paper outlines features of modern miscellaneous targets as well as the combat environment and ECCM environment of air defense radars, and analyzes briefly the position and function of ground based mid and low altitude defense systems in modem air defense. The author believes that these air defense systems can play an important role in modem air defense and would be the preferred weapon especially against such targets as the cruise missile, attack helicopter, lowaltitude aircraft (including stealthy ones) and anti-radiation missile. The article concludes the new requirement of ground based mid and low altitude defense radars, mainly including good ECCM performance, good low altitude property, the required capability of small target detecting for weapon systems, capability of rapid search and acquisition. The realizability of these requirements in ground based mid and low altitude defense systems is also discussed in brief in this paper.
