Методика моделирования процесса обнаружения воздушных объектов наземной обзорной РЛС в условиях воздействия пассивных помех

The article considers the modeling methodology for detection process of air facilities by ground surveillance radar under the impact of dipole passive jamming and natural passive jamming (local objects and the "angel echo" type ja m-ming). The methodology is created to implement this process in a Cosmonauts Training computer system for training combat crews of radar troops subdivisions. There was an analysis of the status and prospects of air and space attack devices and their application tactics. It shows that one way of overcoming air defense system is using radio interference. Electronic warfare provides passive jamming with high intensity. Moreover, passive jamming as reflections from the ground surface (local sub-jects) and from hydrometeors is always in radar receiver. Modeling detection process of air facilities by ground surveillance radar includes considering the capability of radar in jamming environment. It also should take into account origin aspects and impact of jamming on the radar. There are works that present approaches to making jamming models, but these approaches can not be implemented in a ground radar model operating in real time in rapidly changing complex conditions. The purpose of the paper is to provide an adequate and easily implemented modeling process of passive jamming affecting ground radar for using in training systems for training combat crews of radar troops subdivisions. The paper resents relations in formulas for calculating target detection facts when radar is under the impact of natural and artificial passive jamming.
