Abstract: The paper demonstrates a technology of spatial -combination for the random decentralized jammer array by principle analysis, computer simulation and engineering tests. The technology is essentially an application of the active phased array radar theory. It just deploys jammer units distributed and builds up a huge thinning antenna array covering several square kilometers. As a conclusion, this technology not only guarantees the jammers’ mobility and field-viability, but also provides a new possible way to increase jamming power and battle effectiveness.

Key words: short-wave jamming, random thinning array, spatial power-combing
