MULTIFUNCTIONAL ON-BOARD RADAR COMPLEX Russian patent published in 2018 - IPC G01S13/90 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to radar and is intended for solving a wide range of tasks used on manned and unmanned aerial vehicles (UAVs). In a multifunctional on-board radar complex containing a radio frequency module including a dual-band antenna module consisting of two antenna systems for two bands: SHF and UHF wavelength bands, receiver module, SHF and UHF waveband transmitters, the outputs of the receiving module are connected to an on-board digital computer (OBDC), antenna systems are implemented in the form of conformal phased antenna arrays (PAA) with synthesized aperture in printed or waveguide version of metamaterials, the radiating elements of the phased array have directional diagrams of cardioid type, the phased array antenna control unit connected to the radio frequency module control interface is introduced into the antenna module, two-channel SHF antenna arrays are located on the wings of the UAV from below on the left and/or right side or along the side inscribed in the body of the wings or sides, and dual-channel UHF antennas are installed in the UAV stabilizer, all antenna arrays are covered with radioparent radomes that are conformally inscribed into the hull of the wings and stabilizer of the UAV.

EFFECT: reduction of the mass and dimensions of the on-board radar system as a whole, and also improvement of aerodynamic characteristics for the possibility of their use in UAVs.
