Array elements and Frequency Offset Configuration Method of Cantor
Multi-Stage Frequency Offset FDA-MIMO
Abstract
To address the contradiction between a small number of grid lobes and a
narrow main lobe in the range dimension beampattern of conventional
FDA-MIMO radar, a Cantor Multi-stage frequency offset FDA-MIMO(CMSEO
FDA-MIMO) structure is introduced. Moreover, a combination of frequency
offset and array element number configuration methods is proposed. We
derived the relationship between the main lobe width and periodic range
with frequency offset and fractal order. Furthermore, the frequency
offset and array element order relation closed-form solutions for main
lobe invariance and grid lobe reduction are derived. Simulation
experiments demonstrate the effectiveness of the proposed method.
