SYSTEM TECHNICAL SOLUTION OF ELECTROMAGNETIC ADAPTATION

In military radiolocation systems, electromagnetic compatibility includes the provision of joint operation of the elements that make up various military devices, the creation of joint working conditions for devices as elements of different systems, and inter-system activities. The object of the research is military radar equipment. The article describes the main schematic and technical solutions for electromagnetic compatibility in military radar equipment. In addition to the selection scheme, a method for synchronizing the operation of several radar stations that are very close to each other or operate at the same repetition frequency is studied. The subject of the research is the analysis of the electromagnetic compatibility system. The issues of joint selection, practical application, and reduction in the number of electromagnetic compatibility components are analyzed, and various simplifying assumptions are put forward. The essence of what is presented is diverse and depends on the specific situation. Thus, among the measures based on the use of spatial factors, the dispersion of the main radiation directions of radio-electronic devices in space, various methods of limiting radiation at certain volume angles, reception of signals from different directions, and the use of differences in the polarization structure, etc., were identified. The purpose of the research is to analyze the electromagnetic compatibility system in military radar devices. In accordance with this goal, the scientific research work sets forth the following tasks: analysis of the electromagnetic compatibility system in military radar devices; selection, provision, or, if necessary, modification of the system's operating principle; consideration of the planning and distribution of the radio frequency source among the elements included in the analyzed system; practical application of the approach based on the joint selection of electromagnetic compatibility, reduction in their number, and introduction of various simplifying assumptions, etc.; analysis of the general problem of solving the problem of parameters. To solve the tasks set, the following research methods are used: theoretical, mathematical, and comparative analysis. As a result of the research, a time synchronization device is proposed to ensure electromagnetic compatibility and obtain an unobstructed working zone on the indicator screen, depending on the dispersion of radar stations in the area. The use of a time synchronization device will solve system-technical problems, effectively combat mutual interference, ensure the quality of the operator's work, and increase the probability of correct detection.
