최근 전자전 (EW : Electronic Warfare)은 현대전의 핵심으로 자리매김하고 있다. 전자전에서 재밍 (Jamming)은 적군의 통신을 교란시키는 전자공격 (EA : Electronic Attack)을 의미하는 것으로 재밍 전술은공격 대상에 따라서 여러 가지로 나눌 수 있다. 본고에서는 군통신에서 사용되는 전자방해책 (ECM : Electronic Counter Measure)인 재밍 기술을 소개하고, 재밍 신호에 대한 대책으로 재밍 신호를 효과적으로 검출하고 제거할 수 있는 전자방해방어책인 (ECCM : Electronic Counter Counter Measure) 항재밍 (Anti-Jamming) 방안도 함께 분석 소개하고자 한다.

미국 특수전투단에 속해 있는 컴퓨터 바이러스 전투단은 걸프전시 이라크의 미사일망을 교란 시킬 목적으로 컴퓨터 바이러스를 그들의 컴퓨터에 투입하여 물리적인 폭탄보다도 더 위력적인 효과를 발휘하여 연합군의 공격이 감행되었을 때 효과적으로 이라크의 레이다망을 억제하였다.

Usually, a tracking-gate of the tracker is used to track the target radar signal in the active ECM system. In this paper, we propose the feed-back tracking-gate filtering method. The designed method applies a tracking-gate of the tacker to the ECM system's receiver as a rejection or pass filter selected by the receiver's purpose, and the specific target signals can be passed or rejected though this tracking-gate filter. Thus, the number of input signals within the receiver's search band is minimized owing to this filter except the target signals. In conclusion, the EW equipment's reaction time can be reduced and the error value about the target signals can be lower than the previous methods'.

Electronic warfare recently has became the core of modern warfare and the importance of communication survivability is being considerable day by day. In this paper, we propose an effective jamming avoidance algorithm aginst widely used jamming environment such as GPS jamming. In order to simulate to show our system performance, we consider IEEE 802.16 WiMAX protocol and partial band jamming envoriment. Proposed algorithm can improve channel capacity through subchannelization and we show channel capacity corresponding to subchannel parameter.

In this study, based on Privacy Calculus Model, we study whether users' intention of continuous use of closed-type SNS is affected by information privacy concern. In addition, we propose a model that studies if the major factors of the intention of continuous use which are trust, satisfaction and benefits could control the information privacy concern's effect on the intention of use. As a result, companies have to consider protecting the psychological privacy and information privacy of the individual when they design SNS.
