Abstract :
This document presents the design and performance of an active phased array antenna developed for a X-band simultaneous broadband SAR and MTI airborne Radar. The modular architecture of the active antenna is presented, with the major constitutive elements. Details on calibration concept followed by results on the antenna, measured in a near-field range, and on the sensor with the core electronics controlling it, measured in a compact range, are given.
