Abstract
To solve the problem that the traditional 'narrow-band, far-field' resolution formulas are no longer suitable for Impulse Radio Ultra-Wide Band (IR-UWB) real aperture imaging systems, a new algorithm to compute the resolution was proposed. On analysis of IR-UWB near-field imaging principle, the formulation of resolution in down-and cross-range for single antenna was derived. Combined with signal superposition in the process of imaging, an algorithm to compute the resolution for real-aperture uniform linear array was presented. Numerical simulation results of ideal point targets imaging verified the correctness of the algorithm.
