Communications Jamming And Communications Interference Comprehensive Technical Study

It is well known that information warfare is the most important part in modern warfare, so how to get the power to controlling information has already become the primary research object in military communications domain. The more and more complicated situation in war field and sophisticated electronic technique aggravate the contest for capturing information. But anti-jamming communications and communications jamming are still such two independent technique domains that there is no report about their incorporation except some research about one of them.In this paper, the author researched a new technique of the union between the anti-jamming communications and the communications jamming whose object was to solve the problem about how to make them become a unit. That is, when our troops' communications frequency was the same as that of enemy, we must endure that our troops communicated successfully and at the same time jammed the enemy's communications. Because the research about this technique just began, its research method was theory analysis with the help of computer simulation.At first, the author presented the whole ideal, system configuration and typical application about this technique. Secondly, its three subsystems that included spread spectrum communications system, jamming system and adaptive interference suppressing technique were been analyzed theoretically, and their mathematical models and simulation models were been build respectively. Thirdly, the author introduced the technique ideal about how to uniting communications and jamming, which was dynamic distributing the instantaneous frequency tones of communication signal and interference signal in frequency domain associating with adaptive signal processing. From this ideal the technique tactics in four statuses which included DS+FH,DS+DS,FH+FH,FH+DS were been presented and simulated under lots kinds of conditions respectively. Based on the simulation results, the author analyzed the interference how to influence two troops' communications. In the end, a conclusion was been presented that as long as controlled rationally the power of communications signal and interference signal and their instantaneous frequency tones, communications system and jamming system may work at one time, so the technique ideal introduced in this paper was feasible.
