Abstract:
Disclosed are a radar image generation method and an apparatus for performing the same. The radar image generation method includes receiving a received signal received at each of radars that are distributed and arranged; generating an input signal by processing the received signal; generating a support vector based on the input signal; updating the support vector; updating a coefficient corresponding to the support vector; and generating a radar image based on the support vector and the coefficient.
Abstract:
An antenna apparatus for drone identification and an operating method thereof are provided. The antenna apparatus includes: a plurality of horizontal directional antennas; a vertical directional antenna positioned at a center of an area surrounded by the plurality of horizontal directional antennas; a beamforming unit controlling beamforming of the vertical directional antenna and the plurality of horizontal antennas to transmit and receive signals in all directions; and a power supply unit for suppling power.
Abstract:
An identification method and an unmanned aerial vehicle (UAV) detection apparatus are provided. The identification method, as a method for preventing a collision that may occur in a process of detecting and identifying a plurality of UAVs flying in the air, detects a plurality of UAVs in the air and determines a legitimacy of flight of each of the plurality of UAVs using an identification information request message.
Abstract:
An apparatus for allocating channels in a communication system includes: a receiving unit configured to receive terminal information from a plurality of terminals, the terminal information containing information on data transmission/reception schemes of the terminals; a checking unit configured to check the data transmission/reception schemes of the terminals and check interference at channels allocated to the terminals; and an allocating unit configured to allocate primary and secondary channels to the terminals based on the data transmission/reception schemes of the terminals, change the primary and secondary channels based on the interference, and allocate the changed channels to the terminals; and a transmitting unit configured to transmit channel allocation information on the primary and secondary channels allocated to the terminals to the terminals.
