1 - Analysis and Evaluation of Increasing the Throughput of Processors by Eliminating the Lobe’s Disorder
Saeed Talati Seyed Morteza Ghazali MohammadReza Hassani Ahangar Seyed Mohammad AlaviIn modern radars, the design is such that radar vulnerability to noise disturbance is significantly reduced. This dramatic decrease is due to the fact that radars are always trying to increase their capability against the heavy clutter they receive from the ground. Rada چکیده کاملIn modern radars, the design is such that radar vulnerability to noise disturbance is significantly reduced. This dramatic decrease is due to the fact that radars are always trying to increase their capability against the heavy clutter they receive from the ground. Radars use antenna sidelobes to reduce clutter. By reducing the antenna sidelobes, the vulnerability of the radar to the heavy clutches of the sidelobes is reduced, which also reduces the vulnerability to sidelobe disturbance. In this article, we try to examine the reduction of clutter causing the reduction of vulnerability to disorder. پرونده مقاله -

3 - Designing a New CVR Receiver and Investigating the Problem with Simultaneous Signal with Applying Approach in Electronic Warfare
Afsaneh Asgharzadeh Mohammad MirzaeiIn order to launch different receivers in electronic warfare, side-circuits are required to detect the presence of a pulse at the receiver input and to report it after making sure that the receiver output is not due to system noise alone. In practice, a crystal video re چکیده کاملIn order to launch different receivers in electronic warfare, side-circuits are required to detect the presence of a pulse at the receiver input and to report it after making sure that the receiver output is not due to system noise alone. In practice, a crystal video receiver (CVR) is used for this purpose. This receiver provides the required time information (or domain related information) to the other part of an electronic warfare receiver by extracting the received RF signal wave envelope. In this paper, after a conceptual overview of the structure of this receiver, the analysis of its function (sensitivity) will be dealt with. Moreover, some important issues in its design will be discussed. In addition, since the IFM and CVR receivers are not capable of processing simultaneous pulses or pulses coupled with the CW, some further steps are taken to maintain system efficacy under such conditions. پرونده مقاله -

4 - The Use of Electronic Warfare and Information Signaling in Network-based Warfare
Mohammad Reza Hassani Ahangar Saeed Talati Ali Rahmati Hamid HeidariNetwork- based warfare is known as the symbolic element of the Age Information War. The network-based approach has been built around information sharing, and this information sharing in the battle is possible through the networking of all elements on the battlefield. A چکیده کاملNetwork- based warfare is known as the symbolic element of the Age Information War. The network-based approach has been built around information sharing, and this information sharing in the battle is possible through the networking of all elements on the battlefield. A coherent networking force improves the quality of information sharing and, as a result, survival and command speed, improves the efficiency of battlefield elements, saves time and resources, and adds value for combat capability. There are various levels, including the lowest level, that is, an infantry soldier, which ultimately results in an amazing increase in the effectiveness of combat operations. Recent developments in microelectronics, mechanics, and ergonomics, as well as the movement and return, the importance and emphasis from tanks and missiles to soldiers, have examined future soldier projects. Electronic science has led to the integration of small individuals with advanced technology equipment and infantry soldiers with advanced communication, command and control (C3) systems, or communications, command, control, computer and information (C4I). All this was to try to see the infantry soldier as a complete unit instead of a small part of the great force. Each country has its own special soldier project. Considering the importance of the subject, identifying the opportunities and threats facing the Iranian warrior is necessary. In this study, we will study the future soldier project in advanced and sensitive countries and focus on communication and Network- based systems. پرونده مقاله -

5 - Find the Best Answer in the Conflict Scenario of Fighters with Electronic Warfare and a set of Defense Radars without Having Complete Information from Each other
Houman Akbarzade KhoshkeRood Seyed Mohammad AlaviChoosing a strategy for electronic conflicts in the field of action and situations similar to the problem scenario is a matter of experience and will not necessarily be the best possible choice. Therefore, the importance of providing a reasonable and measurable decision چکیده کاملChoosing a strategy for electronic conflicts in the field of action and situations similar to the problem scenario is a matter of experience and will not necessarily be the best possible choice. Therefore, the importance of providing a reasonable and measurable decision-making method in choosing a strategy in real conditions is quite clear. One of the points that can be deduced from the study of common methods and techniques in electronic warfare is that none of these methods are considered absolute winners and the holder can’t consider himself the undisputed winner of the field. Because there is more or less the opposite of any technique. Using a method or tool in a situation may be very effective, but with a change of method or change of tool by the competitor, it becomes a weakness. Therefore, in this battle, the correct and timely use of each technique, and with full knowledge of the opponent and in accordance with the actions performed by him can be considered a factor of success and all useful tools in this field can be used. One of the most useful tools in the field of strategic decision analysis is game theory. With the help of this mathematical tool, the decision-making process between two or more decision-makers can be examined and the results can be analyzed. It is also possible to observe the effect of various parameters involved in the result of the problem, and to plan the result in the desired direction. In this paper, selecting the best response in different stages of the conflict to solve various such problems is achieved and the main purpose is to present a new approach to adopt a strategy and select the radar and disruptive coping technique in case of incomplete information from each other, using a method It is mathematical and algorithmic, so that we have a better performance in the benefit function of the parties. پرونده مقاله -
