RADAR ENERGY POTENTIAL CORRECTION METHOD Russian patent published in 2010 - IPC G01S13/95 

FIELD: physics.

SUBSTANCE: along with an existing real radar channel, a virtual reference channel with a given radar energy potential value is formed, as well as a calibration target in form of a virtual cloud medium with an invariably known level of radar reflectivity. When correcting the radar energy potential, the cloud medium is probed, from which the distance to the analysed local volume of the cloud is determined and the projection of the envelope of the video pulse on the axis of the distance in the real and reference channels respectively is found. Further, the difference in electromagnetic density of the cloud medium between the virtual reference and real channels is found using a calculation method. The radar energy potential is then corrected by determining its true value using the corresponding formula.

EFFECT: more accurate radar measurements through correction of the radar energy potential in each measurement cycle.
