METHOD OF CREATING ELECTROMAGNETIC COMPATIBILITY AREA FOR GROUND-BASED RADIOELECTRONIC EQUIPMENT Russian patent published in 2014 - IPC H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio communication and is intended to provide electromagnetic compatibility of ground-based radioelectronic equipment operating in matching radio frequency bands and in common territorial areas. Probed dislocation points of a transmitting (receiving) device of new radioelectronic equipment are placed at nodes of an equilateral triangular grid, arranged with uniform spacing on the territorial area under investigation relative to the dislocation point (x₀,y₀) of the receiving (transmitting) device of the active radioelectronic equipment; while moving in a selected azimuthal direction on the grid from the point (x₀,y₀) to the dislocation point of the transmitting (receiving) device of the new radioelectronic equipment, the value W=P_I-P_Iall is checked at each point (where P_I is the interference power at the input of the receiving device, P_Iall is the allowable interference power), said value being calculated based on surface topography; movement continues until two neighbouring points (x₁,y₁) and (x₂,y₂), where the values of W have different signs, are found, i.e. when points lying on different sides of the contour are found; said points are considered initial points for constructing boundaries of the area; a third point (x₃,y₃) is then determined, which forms an equilateral triangle with the first two points and lies on the right side of the line formed by points (x₁,y₁) and (x₂,y₂); the value of W at said point is then calculated; if after calculation, the obtained point lies outside the boundary of the area, points (x₂,y₂) and (x₃,y₃) are selected as initial points for the next iteration, otherwise points (x₁,y₁) and (x₃,y₃) are selected; the tracking of the boundary of the area ends when initial points of the next iteration match initial points at the first iteration; wherein at each l-th iteration, a point (x_k,y_k) lying at the side of the triangle and belonging to the contour of the area is determined based on known points (x_l,y_l) and (x_l+1,y_l+1), and the contour of the area is found by interpolating the found points {x_k,y_k}.

EFFECT: high quality of providing electromagnetic compatibility of radioelectronic equipment, faster and more accurate construction of electromagnetic compatibility areas.
