SPACE OBSERVATION METHOD Russian patent published in 2017 - IPC G01S13/00 

Abstract RU 2621680 C1

FIELD: radio engineering, communication.

SUBSTANCE: according to the method, in each azimuthal position of the radiation pattern in the transmission mode, the digital antenna array generates a fan transmitting radiation pattern in the elevation plane, in the receiving mode, the received reflected signals from the antenna element outputs are represented as digital samples from which, by weighted summation, in the angle plane, a directivity pattern with needle-shaped rays. Neighboring rays overlap at half-power level when detecting objects, measuring their range and angle coordinates a monopulse method of signal processing for each of the neighboring pairs of receiving beams is used. The azimuthal coordinate of the detected objects is the current azimuthal position of the radiation pattern. When the antenna system is rotated, the azimuthal position of the transmitting and receiving radiation patterns is maintained by electronically scanning them in the direction opposite to the rotation of the antenna system, until the angular shift of the antenna reaches the value of Δθobs. After that, the hopping movement of the transmitting and receiving radiation patterns is carried out by electronically scanning them to the next azimuthal position, which differs from the previous one by an angle Δθobs. along the antenna system rotatation pattern.

EFFECT: reduction of review time and improving the accuracy of the measurement object coordinates.
