FIELD: radar.
SUBSTANCE: invention can be used for detection and direction finding of surface and semi-submerged drones with low effective scattering area (ESA) less than 0.5 m2. Disclosed radar detection and direction finding system is based on MIMO signals reflected from the target of probing signals, note here that wake water irregularities (turbulent swirls) are used as reflecting elements. Multibeam radar station consists of two parts: spatial and internal. Spatial part comprises trail line, sector of view, probing signals and reflected signals. Internal part contains a receiving-driving antenna unit in the form of one transmitting and three spaced-apart receiving flat phased antenna arrays (PAA), a microcontroller (MC), a driving channel, three digital receivers and a control and calculation device.
EFFECT: high probability of detecting surface drones with low RCS, as well as high accuracy of determining coordinates of surface drones: azimuth angle, range and speed.
