This article presents a design and implementation of the electronically beam steering system for active electronically scanning array (AESA) radar. This beam steering system used look‐up table (LUT) calibration method to calibrate an amplitude and phase errors of each T/R Modules. LUT contains the T/R Module characterization data and the antenna correction data. Performance of this beam steering system was verified with the X‐band AESA radar demonstrator which has 1024 radiating elements and 504 T/R Modules. Beam steering angle is ±60° in each azimuth and elevation. Beam steering time is 3 µs using the precalculation method of the next steering position. © 2014 Wiley Periodicals, Inc.
