Abstract

This study analyses the spatial resolution for the low frequency (LF) ultra-wideband (UWB) one-stationary bistatic synthetic aperture radar (OSBSAR) system. It considers the wavenumber coupling and radar squint angle to derive the finest possible spatial resolution. First, the spatial wavenumber of the LF UWB OSBSAR echo data of the target is analyzed. Then, its spatial resolution is derived based on the spatial wavenumber domain support. Simulation results are given to prove its validity.
