A method for the angle determination in the case of multi-target scenarios for more lobes - mono pulse radar

摘要

The present invention relates to a process for the angle determination in the case of multi-target scenarios for more lobes - mono pulse radar, wherein by means of one or more antennas in the azimuth - plane a plurality of beam lobes are formed, which overlap one another in pairs in partial regions and via which the radar signal at the same time or in a time sequence or by way of a separate antenna and the reflected signal is emitted via the beam lobes also simultaneously or in a time sequence or by way of a separate antenna is received and processed further.It is an algorithm is provided, which for the separation of the signal portions of the individual targets essentially the following process steps includes:Determination of two adjacent beam lobes (n), determining the angular position of the respective destination from the two selected signals of the adjacent beam lobes (n), obtaining a standardized "ideal " einziel - signal pattern (z_n), The formation of the scalar product (s_j) according to the equation s_j = Σ_n S_n · Z_n (α_j)*, Determination of the signal amplitudes (s_n^newly) according to the equation s_n^newly = S_n - s_j · Z_n (α_j), Checking of the signal amplitudes (s_n^newly) on the basis of a threshold and starting of a new cycle with (s_n^newly) as an input variable.
