The rapid development of sophisticated military command and control systems causes the dynamic demand for broadband services including the transmission of video in real time by using telecommunications links. One way to resolve the problem of limited bandwidth in used military wireless systems is to use modern broadband radio stations. Broadband radio stations in addition to undoubted advantages such as increased system bandwidth, have also some limitations – in comparison to narrowband radios, broadband radios offer a smaller range and work in a wide band and high transmitter activity associated with the generation of maintenance traffic, which makes it easier to detect radio emission by the opponent. Modern electronic warfare systems can track down such systems and overpower them. That is why one of the main tasks, which currently are facing designers of advanced broadband radio communication systems, is to develop mechanisms to immunize broadband radio stations on the targeted interference. In this article the method of implementation of the national waveform allowing for securing the transmission in broadband radio stations will be presented. Transmission modes of the radio station (TDMA, CSMA/SC, CSMA/MC) will be discussed considering advantages and disadvantages of each of the above-mentioned modes of operation. In the next chapter selected results of experimental studies of broadband radio station R-450C with the above-mentioned implemented operating modes and universal defeat device for generation of diverse broadband interference will be presented. The obtained results will allow to assess the implemented modes of radio stations for resistances of broadband radio communication system on selected targeted interference. The developed analysis and obtained measurement results may be helpful both for people organizing radio communication using broadband radios as well as for those responsible for the proper operation of electronic warfare systems.

Modern systems of radio communication planning have two aims: ensuring both internal and external compatibility of the system (i.e. avoiding both interference within the network and jamming or interference by other sources). Currently, systems of planning concentrate only on ensuring internal compatibility of the radio system and avoiding usual interference from external sources. The part of ensuring external compatibility of the radio system related to avoiding jamming was carried out by using appropriate mode of radios, ex. frequency hopping mode, free channel search mode, etc. With this approach, we had no information about efficiency of the methods used. In particular, we had no information whether we have made the radio nets immune to jamming. We present a model of planning frequency assignment by a mobile military communication network taking into account not only internal interference of planner's own system but also potential presence of a rational opponent.

To do this, we use dynamic games with incomplete information and the concepts of belief distorted Nash equilibria, both in deterministic and stochastic form of expectations. This analysis allows us to find remedies to several types of behaviour of the opponent. From theoretical point of view, in existing approaches, the problems of frequency assignment for a mobile military communication network in various time instants are treated as independent static optimization problems with only one decision maker. First of all, we have to be conscious, that we face not a simple optimization problem, but a game: besides our communication network, there may be an opponent, whose aim is to detect and/or jam our transmission. Besides, a dynamic character of interaction has to be taken into account: using a plan of frequencies defined a priori and switching to the same reserve plans in predetermined way whenever jamming appears, makes it possible for the counteracting unit of the opponent to uncover the rules of our behaviour. Using dynamic game theory, in particular dynamic games with incomplete information, allows us to utilize information about rules of behaviour of the opponent during the process of frequency planning. The side which takes the dynamic character of the decision making problem into account as the first can benefit from this fact.
