In this paper the importance of electronic warfare is presented taking into consideration the information age environment. In order to understand the electronic warfare this in information age, first we should understand what information age is and how the electromagnetic spectrum is used today. The Information age has changed every aspect of our life. For the first time in history we can create, access and store a high amount of information and all this happen during our life span. How has the military field been affected by all these changes? The military answer to the information age was the network centric warfare (NCW). As we can see, this concept NCW is affecting every aspect of the military field creating the evolution path from platform-centric to network-centric forces. When all military tools are physically limited in order to achieve military superiority we should exploit the new domain the information domain. Without this transformation it is not possible to achieve victory。

Traditional speckle fringe patterns of electronic speckle pattern interferometry (ESPI) are obtained by adding, subtracting, or multiplying the speckle patterns recorded before and after the deformation. However, these speckle fringe patterns are of limited visibility, especially for addition and multiplication fringe patterns. We propose a novel method to obtain speckle fringe patterns of ESPI from undeformed and deformed speckle patterns. The fringe pattern generated by our method is of high c

We study an electronic compensator (EC) as a receiver for a 100-Gb/s polarization division multiplexing coherent optical orthogonal frequency division multiplexing (PDM-CO-OFDM) system without optical dispersion compensation. EC, including electrical dispersion compensation (EDC), least squares channel estimation and compensation (LSCEC), and phase compensation (PC), is used to compensate for chromatic dispersion (CD), phase noise, polarization mode dispersion (PMD), and channel impairments, res

Many research groups in academia and industry are focusing on the performance improvement of electronic nose (E-nose) systems mainly involving three.optimizations, which are sensitive material selection and sensor array optimization,enhanced feature extraction methods and pattern recognition method selection. For a specific application, the feature extraction method is a basic part of these three optimizations and a key point in E-nose system performance improvement. The aim of a feature extract
