METHOD OF THE TWO-STEP RADAR SCANNING OF SPACE (OPTIONS) Russian patent published in 2017 - IPC G01S13/04 

FIELD: radio engineering, communication.

SUBSTANCE: according to the method of two-stage radar scanning of space, including the range measurement of detectable target, the space is scanned by a composite signal consisting of a time-limited broadband signal and its parts, spread out over a period of time. And for the range resolution an interpulse signal is used and for the Doppler speed resolution and measurement its parts, spread out over a period of time, are used. The second option in the method of two-stage scanning of space, which includes the range measurement of the detectable target, the space is scanned by a composite signal consisting of a time-limited broadband signal and its parts, spread out over a period of time, the Doppler speed is defined, all the parts of the composite signal are coherently summarized at long range, and are checked for a match at short ranges.

EFFECT: detection of the target, namely the detection of the fact of the presence of the target in the examined direction and the determination of its location - angular coordinates and range; in addition, for radar stations with short range - maintaining a high rate of view and the ability to allocate high-speed targets.
