In this paper we go through design, fabrication and evaluation steps of the 7 m linear antenna operating between 2 and 4 GHz dedicated to the land-mine detection radar. It consists of 128-switched elements of loaded Vivaldi type arranged in 16 sub-arrays. We have successfully conducted preliminary tests.

A wideband antenna array is developed for the land-mine detection in the desert with an on-board radar. The final array is very large and contains 128 Vivaldi antennas. The array is split into 16 sub-arrays of 8 elements. Each Vivaldi antenna is driven independently by electronic switches for SAR imaging purpose. In a first step, a sub-array of...
