This paper describes an Automated Change Detection and Classification (ACDC) system being developed by the Naval Research Laboratory (NRL) for the Mine Warfare group at the Naval Oceanographic Office (NAVOCEANO). ACDC autonomously detects features in sidescan imagery, classifies the features, searches through historical and dynamic databases of previously detected features and performs change d...

As radar signal environments become denser and more complex, the capability of high-speed and accurate signal analysis is required for an ES(Electronic warfare Support) system to identify individual radar signals in realtime. This paper presents the adaptive clustering algorithm of radar pulses to alleviate the load of signal analysis process and support reliable analysis. The proposed clusteri...

INTRODUCTION We have seen a rise in computer misuse at a global level and also the development of new policies and strategies to describe organized computer security attacks against the information society–these strategies are described as being “information warfare.” This is very different from the traditional view of attack against computers by the individual, determined hacker, a cyber warri...

As Defense agencies and services expand their reliance on computer networks, risk to information availability and integrity increases. It is no longer adequate to rely solely on the now traditional defense-in-depth strategy. We must recognize that we are engaged in a form of warfare, cyber warfare, and deploy our resources using the strategy and tactics of warfare. Most Defense organizations ha...

The authors sum up the more capital questions of the asymmetric warfare and its psychological factors. They give overview about the military-scientific basis of the asymmetric warfare and its threats; interpretation of asymmetry in the activities of national security; Systematic elements of strategic asymmetry; coherence of strategy reacting to asymmetric threats with other strategies and final...

Radar emitter signal recognition is one of the key procedures in signal processing of Electronic Intelligence. To enhance the ability of online recognition to meet the requirement of modern electronic warfare, A novel recognition approach for radar emitter signals based on on-line independent support vector machines is presented in this paper. Based on the cascade feature extraction of radar em...

This study aims to evaluate the accuracy of a method proposed for passive localization radar emitters around irregular terrains with single receiver in Electronic Support Measures systems. Previously, authors targeted only theoretical development method. In fact, this could be serious concern practice since there is no evidence regarding its under real data gathered from realistic scenarios. Th...
