Disclosed are a communication technique which merges, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. A beam forming method for an array antenna, according to one embodiment of the present disclosure, can comprise the steps of: setting a first area and a second area for beam formation; calculating a first directivity function corresponding to the first area and a second directivity function corresponding to the second area; setting an objective function on the basis of the first directivity function and the second directivity function; determining a feed coefficient of the array antenna on the basis of the objective function; and forming a beam on the basis of the determined feed coefficient.

Optimization method and apparatus for efficient beam synthesis

A method of assisting an autonomous vehicle includes obtaining first surrounding area information of the vehicle when the vehicle is located at a first distance from a monitored area disposed ahead of the vehicle, providing a first control command for controlling the vehicle to operate in a first operating mode, by using the first surrounding area information, obtaining second surrounding area information of the vehicle when the vehicle has driven toward the monitored area and is located at a second distance less than the first distance from the monitored area, and providing a second control command for controlling the vehicle to operate in a second operating mode, by using the second surrounding area information.
