Abstract

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.
