The method for determining the height of two-coordinate radar target

摘要

A method for determining target height two-coordinate radar comprising detecting abnormalities in the dynamics of the changes recorded by the radar target coordinates and calculation laws to change them with the desired height of the target motion on the assumption that the target is moving in a radar coverage area rectilinearly at a uniform rate, and XY radar of the characteristics of the target position are determined only by the distance and bearing relative to the radar, and the assumption that they have a vertical pattern that is different from zero, so that Radar coverage area fall objects moving at a certain height, the configuration of the three measurement target and radar form a triangle, and every two adjacent measurement target with radar form triangles, with the common side of a median, which is calculated on the two sides and the angle between them and taking a constant height H aims of the movement; thus, components of the system of equations whose solution gives, when specifying koeffitsientovK = - (AB) + 4 · (AB) - (AB), L = 2 cos α, the following biquadratic equation of the fourth degree (4-L) H + (L · (AB) -4K + L · (AB)) H + (KL · (AB) (AB)) = 0, the root of the equation are two heights, one of which is misleading, which is eliminated by comparison with the calculated heights for the following iterations method.
