Simulation & Presentation of Optimized Techniques for Stealth Airborne Electronic Warfare Systems Using by OFDM Modulation

On the battlefield, the basic air-defense systems do not use a variety of techniques for electronic defense, and therefore are involved in hard and soft threats. In this paper, OFDM modulation technique that improves stealth technologies in airborne system are analyzed and simulated. The parameters affecting the stealth techniques such as increased bandwidth and reduced power spectral density and power of side lobe (PSL) are calculated and presented. And also the transmitting random subcarrier technique is presented. In this technique, due to not knowing intercept systems from transmitting subcarrier and also discovery and detection of airborne systems, electronic warfare happens with difficulty that causes deception. This kind of techniques will be useful for stealth of air borne system designers with electronic defense.
