METHOD OF CONSTRUCTING A RADAR STATION Russian patent published in 2020 - IPC G01S13/00 

FIELD: radar ranging.

SUBSTANCE: invention relates to radar ranging and is intended for construction of radar stations (RS) for various purposes, for example, air traffic control, meteorological, etc. Result is achieved by emitting a probing signal and receiving reflected signals by an antenna system (AS) in the form of a flat phased antenna array (PAA), installing AS on the rotary support device (RSD), installing PAA antenna elements on the front panels of multichannel transceiving modules (TM) with pitch between them along the vertical and horizontal, determined by the required sector of electronic scanning, respectively, in vertical and horizontal planes, each antenna element is connected to antenna input / output of one of channels of multichannel TM, PAA antenna band is formed from multichannel TM, by placing them adjacent to each other so that surfaces of their front panels are located in one plane, and distance between antenna elements remained invariable in vertical and horizontal planes. In the transmission mode, a probing signal is generated, in the transmitting part of each transceiving channel (TC), the phase of the probing signal is changed using a phase shifter and amplified in a solid-state power amplifier such that a transmitting directional pattern (DP) of a needle-shaped or fan-shaped is formed in the space, the width of which is determined by the required angular size of the detection zone RS. In reception mode, in each TC, the received signals are amplified, converted by frequency, signals from the channels outputs are converted into digital form, wherein obtained samples are used to form a multibeam receiving DP, each beam of which has a needle shape, and adjacent beams overlap in half-power level, wherein the receiving DP width corresponds to the transmission DP width, the objects are detected, their range and angular coordinates are measured using the monopulse signal processing method of each of the neighboring pairs of the receiving beams, wherein for scanning in a limited sector in the azimuth, electronic tuning of the receiving and transmitting DP with the fixed antenna system is used, and for rotation in the azimuth, the rotation of the AS using the RSD is used.

EFFECT: reduced time of space survey.
