The article describes the main components of the process of imitational mathematical modeling of the radio-electronic and objects environment:
- the scenario of changes in the radio-electronic and objects environment;
- principles of modeling of separate radiations of radioelectronic devices and functioning of objects as an aggregate of radio-electronic devices;
- principles of modeling of separate devices of radio monitoring and monitoring system, as a set of devices of radio monitoring, functioning for achievement of the uniform target and on uniform algorithm;
- data exchange environment between simulation
mathematical models of these elements.
Under the radio-electronic and objects environment (REOE) should be understood a set of stationary and mobile objects and radio electronic devices (RED) of air, ground and sea bases, which perform the tasks of controlling forces and means by emitting and processing radio signals. REOE is usually considered within the specified limits of space, frequency range and time.
To obtain information about the location, classes (types) of such objects, the state of their electronic devices, in a time scale close to the real one, it is necessary to create systems for monitoring the electronic object environment (SM REOE).
The following tasks are assigned to SM REOE [1-6]:
- collection and processing of information about objects and RED located on them;
- determining the location of objects and RED,
establishing correspondence between RED and objects on which they are installed, and maintaining the trajectories of their movement;
- recognition of types of RED, modes of their work, classes (types) of their carriers;
- display of the received information about objects and radio emissions from them;
- assessment of REOE in the region.
Estimation of REOE consists in complex processing of the information on coordinates and parameters of movement of objects, and also signals which they emit various on structure, rates of receipt and parameters of accuracy.
The quality of functioning of CM REOO is generally
determined [1, 4, 5]: - the composition of the forces at the disposal of the system and the tactical and technical characteristics of the means used to obtain information about the radiation and objects that are their sources; - placement of forces and means of monitoring in space; - algorithms for complex processing of information about coordinates, motion parameters of objects and radio signals emitted by them; - algorithm of functioning of all monitoring system.
CM REOEs are complex systems. When building and improving such systems it is necessary:
- assess the quality of functioning of construction options, according to a certain system of indicators and criteria and make an informed decision on the best of the options; 
- evaluate the quality and perform settings of algorithms for collecting and processing information, both in individual monitoring tools and in the system as a whole;
- train operators of monitoring tools and assess its quality, etc.
To solve such problems, a system of simulation
mathematical modeling of REOE has been developed.
The purpose of the article is:
- presentation of the main results of the development of a simulation system close to real-time dynamic REOO and its monitoring systems;
- demonstration of possibilities of application of the developed scientific-methodical and program-algorithmic device for adjustment of process of work of system of radio monitoring, optimization of its structure, adjustment of algorithms of functioning of means of radio monitoring, estimation of efficiency of the decision of separate problems of radio monitoring and system as a whole.
The possibility of application of the developed
scientific-algorithmic device for optimization of structure and adjustment of algorithms of work of system of radio monitoring and its separate components is shown.
