摘要
Abstract
The jamming implementation is difficult for Direct-Sequence Spread-Spectrum ( DSSS) signal because of its character-istics such as low-power spectrum density transmission invisibility,high anti-jamming capability,low probability of detection (LPD), etc.In order to realize better jamming effect,it must ensure that the power of jamming signal de-spreaded by receiver is high enough. Based on the characteristics of the spread-spectrum code of DSSS system,this paper builds a math model,and calculates the relation be-tween the output power of signal at the end of receiver and relative bandwidth under a certain input power of jamming signal.This is to say,there is an optimal relative bandwidth,which makes the highest output power of jamming signal,and can ensure an optimal jamming effect.关键词
