METHOD FOR RADAR SCANNING OF SPACE , RADAR STATION THEREFOR AND RADAR TRANSMIT MODULE Russian patent published in 2018 - IPC G01S13/00 

FIELD: radar ranging and radio navigation.

SUBSTANCE: inventions relate to the field of radar and can be used in radio-detection stations (RDS) of the all-round view – surveillance radars, designed to work in conditions of intense passive interference, for example in mountainous areas, as well as in cases where the measurement of the radial velocity of the target is required in surveillance radars. Inventions are based on the principle of increasing the radar operation capabilities for its application under the conditions of intense passive interference due to its acquisition with an additional radar module, which may be a radar transmitting module. As a result, a single complex of monostatic and bistatic radio-detection station will be formed from the two radar tools while retaining the advantages of each of them. This result is also achieved by using different antennas for transmitting and receiving signals with target resolution in terms of speed: for transmitting, a radio-detecting module (RDM) antenna, and radar antennas for receiving. At the same time, space is probed by a signal with a resolution of targets for speed using RDM, and when a moving target is detected by this signal with a radio-detection station, it is also probed by signals with a resolution of targets in range; using radars, they simultaneously receive their own reflected signals and reflected signals of the RDM with the exception of the time interval of sensing space by signals with the resolution of targets in range; as radar use radio transmitting module (RTM). To use the radio-detection station under the conditions of intense passive interference, it is equipped with RTM, whose input is connected to the control output of the radar, and a channel is added to the radar receiver to receive reflections of the probe signals emitted by the RTM, which contains an antenna for emitting probe signals with a speed resolution and a transmitter connected to it for forming them or transmitting an active phased antenna array.

EFFECT: ensuring unambiguous resolution of targets by the Doppler velocity and its measurement through the use of long-pulse or continuous probing signals while maintaining the possibility of resolving targets in range.
