Goryachaya Liniya-Telecom press has published a book written by IRCOS JSC officers, titled Automated Radio Monitoring Systems and Their Components (in Russian). The authors are: A.M. Rembovsky, A.V. Ashikhmin, and V.A. Kozmin. Edited by A.M. Rembovskiy, the Doctor of Engineering.



The book is based on results of research carried out by engineers, programmers and research assistants of IRCOS JSC. Theoretical and practical problems in construction and application of automated radio monitoring systems for civil and governmental structures including their components: technical means of radio monitoring, the software and engineering infrastructure are considered. The scalable architecture, application of web-technologies, a possibility to use the equipment from different manufacturers, the event mechanism of test fulfilment and effective self-diagnostics are the typical features of considered systems. The constructive solutions, characteristics of modern technical means for radio monitoring and their application are given. A great attention is paid to methods of digital signal processing: detection, direction-finding, measurement of radio signal and interference parameters, radio emission source identification and localization. Practical implementations of described methods are presented in applied software packages and in radiomonitoring equipment.

An article “Virtual Antenna Array Theory and Applications” was published in “American Journal of Electromagnetics and Applications”. Vol. 3, No. 1, 2015, pp. 1-11.. The authors are research workers of IRCOS.

In this article the authors present a physical basis of virtual antenna array method which is based on electrodynamic principle of field source equivalence. It is demonstrated that the virtual antenna array method helps increase radio emitters angular coordinates accuracy by eliminating the error caused by scattering of initial wave on objects near “physical” antenna array. At this no data about antenna array carrier body geometry and material properties is required. Potential use of this method is also provided.

An article “Use of Artificial Dielectric for Improvement of Printed Biconical Vibrator Matching” was published in “American Journal of Electromagnetics and Applications”. Vol. 2, No. 6, 2014, pp. 49-52... The authors are research workers of IRCOS.

This article shows that use of artificial dielectric in form of two-dimensional array consisted of small plates can transform electrical input impedance of printed bi-conical vibrator in ultra-wide bandwidth and improve quality of its matching. It is also found that use of this artificial dielectric eliminates deep dip in radiation pattern of planar bi-conical vibrator in direction normal of its plane at high frequencies.

This year our company participates in MILIPOL 2009 International Exhibition which will be held November 17-20 in Paris, 1 place de la Porte de Versailles Pavilion 1 75015 (France). At our exhibition stand, we are going to present our most advanced products including panoramic receivers, equipment for technical surveillance contra-measure, automatic direction finders and measuring receivers.

Thus, we would like to emphasize the following products from our range:

  1. ARTIKUL-H1 Manpack Wideband Automatic Direction Finder. We could not find anything similar in available technical papers, Internet or catalogs of other companies. This device can detect emitters when moving and show them on a map. It can be carried by operator (max. weight 14 kg, up to 4 hours of battery runtime) or mounted on a car. Also, it can be used with an antenna system installed on max. 4 meter mast.
  2. One more interesting innovation of our company is ARC-RP3M Handheld Direction Finder. This device is based on ARGAMAK-M – our most advanced lightweight compact panoramic receiver with low power consumption. Due to these features, the working weight of the operating set is max. 3.5 kg. This direction finder can process signals in an extended mode – it can detect and take bearings of broadband, Wi-Fi, WiMax, BlueTooth, DECT and other signals. The device can detect broadband batch communication transmissions even if their duration is as low as 50 microseconds.
  3. Also, we would like to present you for the first time at this exhibition our new device - ARC-D1TM-8. This is a multi-functional portable unit designed to monitor radio environment and inhibit unauthorized data transmission in the range from 9 kHz to 8 GHz. It includes a full set of antennae rated for that frequency range and a new special short-wave magnetic antenna – ARC-MA2.
  4. We would be also glad to demonstrate our ARC-D11 Two-Channel Panoramic Radio Receiver, which is the most universal product in our range. At this exhibition we will present for the first time a joint operation of ARC-D11 and AS-HP1 – a compact antenna system for direction finding within the range up to 3000 MHz.
  5. Finally we would like to demonstrate our measuring and instrumentation equipment: ARGAMAK-IM Panoramic Measuring Receiver and ARGAMAK-IS Panoramic Field Strength Meter. The latter unit has a unique design feature. It includes two separate modules – a signal digital processing module and a module comprising both receiving measuring antenna and a signal converter. This feature enables using the remote field transmitter for a distance up to 100 m from the digital processing module without loss of signal. At presentation, our measuring equipment will use SMO-BS1 software for GSM base station analysis.

We will be glad to see you at our exhibition stand No. 13D012 at the first hall of the Exhibition Complex.
