文章介绍了从地对空干扰机的发展概况，从单一干扰轰炸瞄准雷达，发展成地对空干扰系统和系列，可以干扰空载作战飞机雷达、导弹制导雷达、精密制导雷达、预警机雷达、星载探测雷达等，分析了这些雷达的干扰原理、干扰方法和干扰机的布局。文章对新体制雷达的干扰压制系数进行了分析，导出各类新体制雷达的干扰压制系数表达式，并提供了计算机仿真和实际试验的结果。文章分析了90年代以来两次现代化局部战争，地对空干扰系统若能发挥作用，将使被入侵国家的损失率下降，使入侵者的损失率升高。地对空干扰系统具有攻防兼备的立体干扰系列功能，需要经费较低，很适合于第三世界国家的需求，具有广泛的发展前景。

This paper describes the development of the ground-to-air jammer. Initially this equipment can only jam the bomb-aiming radar, but now it has evolved into a ground-to-air jamming system or series, which can jam a variety of radars , including airborne radar on combat aircraft, missile guidance radar, precise guid-ance radar, AW ACS radar and sat ellite-borne radar, etc. The paper analyzes the jamming conception, methods and jamming station configuration against these types of radars.

The paper provides the conceptual analysis of the jamming suppression factors taken for jamming new types of radars, derives their mathematical expressions, and gives both the computer-simulated result and real-test result to further prove the confidence of the theoretical analysis.

The paper notes that in 2 current conflicts in 1990s, the intruders won the wars with very low loss rate (only several parts of ten thousands), because the other side had not equipped with the ground-to-air jamming systems. If they had got the ground-to-air jamming equipment deployed in their air defense system, they would have supported their air defense system to function well, reduced their own loss rate, increased the enemy´s loss, and made intruders not to win so easily.

The paper concludes that the ground-to-air jamming system plays a very important role in the national defense. It has both defensive and offensive functions with its 3D jamming capabilities. Also it is very, cost effective and quite suitable for the developing countries. The ground-to-air jamming system will have a bright future.
