METHOD OF DETERMINING AZIMUTH OF OBJECT WITH HELP OF INTERPOLATED DIRECTION-FINDING CHARACTERISTICS Russian patent published in 2017 - IPC G01S13/44 

FIELD: radio engineering, communication.

SUBSTANCE: method of determining the target azimuth using the interpolated direction-finding characteristic includes processing the stored full azimuth sequence of signals from the output of the monopulse antenna system. The processing excludes signals below the level of reliability of the results determined by the amount of noise in the receiving path. Then, through the points lying to the right and left of the approximate direction to the target, formed by the set of angular positions of the monopulse antenna system and the corresponding signal values from the output of the sum-difference discriminator, interpolated curves of the third order, including these points, the azimuth corresponding to the point of intersection of these curves is the calculated azimuth of the target.

EFFECT: adaptation of the use of a monopulse antenna system to improve the accuracy of target direction finding when exposed to factors that distort the direction-finding characteristics.
