Short-range rotational sar imaging of indoor environments using UWB OFDM sensor

In this paper we discuss the SAR processing algorithm and results associated with the ultra-wideband (UWB) orthogonal frequency division multiplexing (OFDM) system. An efficient method of OFDM SAR imaging for strip-map configuration has been proposed before; in this work we expand upon it and add a new configuration - rotational SAR. We derive the relevant parameters of the rotational SAR system; explore challenges associated with extremely short-range UWB rotational SAR imaging; and present simulation results of imaging point-like targets in presence of noise.
