Recently, it is shown that the channel polarisation phenomenon of Arikan's polar codes with their original multilevel construction happens in several levels with perfect, partially perfect and useless bit channels. On the basis of this construction, this study aims to illustrate design principles and decoding steps of cooperative decode-and-forward polar coding schemes for half-duplex relay channel...
In this paper a complete airborne system was proposed, which consists of two subsystems, the first one is airborne radar that can detect high speed air targets in all environments, and the second one is deception jammer source for countering the ground radars as a supported immunity system for the airborne radar. The novel airborne radar system can overcome the problems of range migration, Doppler...
This paper proposes a new advanced model for deceptive jamming from an airborne jammer source using DRFM based on Sub-Nyquist sampling theorem. The Shannon-Nyquist theorem shows that under sampling with lower sampling rates will be useful in generating a multiple deceptive false target signals with a better resolution, the influence of the false target signals on the ground radar receiver (victim...
The airborne radar is used mainly to detect the ground moving targets, but in case of detecting high speed air target the range migration and Doppler ambiguity estimation will happen in the process of targets parameters estimation, these problems occurs due to the high relative speed between the targets and the airborne radar specially in the presence of jamming and clutter effects that will be more...
