The article deals with their possible use for military identification of chemical warfare agents and their precursors. Spectra of 29 chemical substances were recorded. Based on the similarity of the spectra in the library, the device was able to automatically detect 20 substances in all measurement methods, 1 substance only in the most transparent containers. By means of external software and the creation of a user’s library, the vibrations of functional groups in the respective molecules were assigned to the individual Raman bands, thereby creating a database that enables the identification of toxic substances.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48228598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local air defense is organized to protect assets from these strikes. This takes into account the possible directions of cruise missiles strikes and the effectiveness of assets protection. The effectiveness of assets protection from cruise missiles strikes is assessed by the probability of their preservation, which is determined using the developed methodology based on a simulation model of air defense. The method allows taking into con-sideration the impact of the peculiarities of the cruise missiles usage and the peculiarities of the air defense functioning on the effectiveness of assets protection, in repelling cruise missiles strikes. The application of the method is shown in an example.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45179508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intercepted communication is transformed into behavioral feature vectors that are reduced (using principal component analysis and stepwise selection methods) and normalized to create training and test sets. A feed-forward artificial neural network is then used as a classifier to determine the type of malicious communication. Three training algorithms were used to train the neural network: the Levenberg-Marquardt algorithm, Bayesian regularization, and the scaled conjugate gradient backpropagation algorithm. The proposed artificial neural network topology after reducing the size of the training and test sets achieves a correct classification probability of 81.5 % for each type of malicious communication and of 99.6 % (and better) for normal communication.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49463403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main focus is on the issue of maintaining the maximum signal strength during vehicle movement, gyroscope and GPS sensors error and the deterioration of reception due to changing conditions (weather, obstacles). Typically used techniques are based on ad-hoc scanning of the maximum value of the RF signal. The approach presented in this article might be used as a much more consistent and elegant alternative to these algorithms. To prove the function of the presented algorithm, simulations of several different scenarios are performed. Based on these simulations, the robustness and speed of the newly designed algorithm are evaluated.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41633576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this article is to compare medium-load and high-mobility means of transport belonging to the Polish Armed Forces and to identify the vehicle with the best parameters. The Analytic Hierarchy Process method was used for this, and this paper approximates its assumptions and process. Seven vehicles currently in use by the Polish Armed Forces were compared. As a result of the analysis, a hierarchy of the studied vehicles was established, ranking them from the highest to the lowest rated. The paper allows to assess whether the currently purchased Jelcz 442.32 is a good choice in the procuring policy of the Polish army.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47663718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines the possible increase in survivability of a battalion command post from the effects of enemy artillery fire by deception prior to electronic signature detection by extending the antenna of radio communication assets. Using modelling, the areas of possible command post locations, the exact command post positions and the areas of artillery fire were marked in a geoprocessing tool. Statistical methods were then used to evaluate the success rate of command post destruction. Since there are no documents available that address this issue, the results of this research will allow an assessment of the effectiveness of this measure.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44591368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of these couplers on the end performance of the system have been studied and compensated for by suitably modifying the impedance matching lines (ML).

Combining a micro-balloon hydrogen system with the cryogenic oxygen storage is the best solution for the propulsion.
