SPACE RADAR SCANNING METHOD Russian patent published in 2019 - IPC G01S13/44 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to the field of radar equipment, and can be used in the construction or upgrading of rotating multifunctional radar systems (RMRS) with two-dimensional phased antenna arrays (PAA) with electronic scanning for airspace observation. Radar space observation method is based on the use of a RLS, consisting of one phased antenna array with electronic scanning in elevation and azimuth with simultaneous mechanical rotation of the antenna in azimuth, in which, in the tracking mode, for the targets coordinates measuring in azimuth and elevation the monopulse method is used, the given circular space in fixed angular directions observation is performed at several antenna turns, previously detected targets automatic tracking, linking paths on new targets during the rotating antenna passage of the electronic beam control (EBC) azimuth sector by the beam repeated multiple directing to the point with coordinates, where their initial detection took place, the antenna rotational speed is chosen so that to ensure the required period of addressing to the tracked targets, using sent to each angular direction probing pulses packets, which duration is equal to the observation minimum period in the absence of false detections, targets and pauses, averaged over all angular directions and divided by the number of fixed observation positions, dividing the EBC azimuth sector into two unequal parts, the front in the antenna rotation direction and the rear one, and before each probing pulses packet sending, performing the being executed function dynamic selection in the priority order, namely, the paths linking, automatic tracking, scanning, wherein during the scanning, the beam setting direction is chosen so that if the maximum pause after the last scanning in all observation directions in the rotating EBC sector τ_s rear part, exceeds the same maximum pause for this sector τ_p front part during the antenna rotation outside the electronic scanning sector δt, then choosing the scanning direction from the sector rear part, in which there is a maximum pause, if the pause τ_s do not exceed pause τ_p for a time δt, then choosing the scanning direction from the sector front part, in which there is a maximum pause.

EFFECT: increase in the space observation speed.
