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.
