METHOD FOR DETECTION OF SPEED AND MOTION DIRECTION FOR CARRIER OF SURVEILLANCE RADAR Russian patent published in 2010 - IPC G01S13/58

Abstract RU 2390038 C2

FIELD: radio engineering.

SUBSTANCE: in j receiving point, where , j≠g, bearing is detected for surveillance radar β_j, as well as frequency of surveillance radar signal f_0j, and these values are sent to leading receiving point. In leading receiving point bearing is defined for surveillance radar β_g, as well as difference of frequencies ΔF_gj=f_0g-f_0j, where f_0g - frequency of surveillance radar signal measured by leading receiving point. Angle is calculated between vector of surveillance radar carrier speed and line that connects carrier of surveillance radar and j receiving point, and also speed of surveillance radar carrier by certain calculation formulas.

EFFECT: increased accuracy and reduced time for detection of speed and motion direction of surveillance radar carrier in multi-position passive surveillance radar.
