Storozh V. Devices and systems based on the electromagnetic field perturbation for objects defense and control

Dissertation is devoted to models development of the electromagnetic field perturbation process by the extraneous dielectric body and creation on this basis of highly-effective devices and systems for defense and control of important objects. A model of the perturbation process of the electromagnetic field by the extraneous body represented by the system of current filaments has been developed. The analysis of sensor's model in the mode of modulation reception of the reflected from the moving body signal is carried out. The influence of the parasite modulation on the parameters of sensor is studied. As a result, the sensor based on antenna-oscillator, where the reflected signal modulation is provided by the pattern commutation means, has been developed. Peculiarities of the sensor sensible areas formation and a form control were investigated. The constructions of two-frequencies sensors based on antenna-oscillators were developed. The radiating cable and system of two linked lines models with a perturbation discontinuity were developed. As the result of models analysis, the method of smoothing of sensitiveness is offered for the protection and check system on the radiating cables. A wideband system of perimeter protection with improved noise immunity on the radiating cables was developed and studied. Results of theoretical researches are confirmed experimentally.
