  This paper illustrates the potential of an Integrated Sensing and
Communication (ISAC) system, operating in the sub-6 GHz frequency range, for
Synthetic Aperture Radar (SAR) imaging via an Unmanned Aerial Vehicle (UAV)
employed as an aerial base station. The primary aim is to validate the system's
ability to generate SAR imagery within the confines of modern communication
standards, including considerations like power limits, carrier frequency,
bandwidth, and other relevant parameters. The paper presents two methods for
processing the signal reflected by the scene. Additionally, we analyze two key
performance indicators for their respective fields, the Noise Equivalent Sigma
Zero (NESZ) and the Bit Error Rate (BER), using the QUAsi Deterministic RadIo
channel GenerAtor (QuaDRiGa), demonstrating the system's capability to image
buried targets in challenging scenarios. The paper shows simulated Impulse
Response Functions (IRF) as possible pulse compression techniques under
different assumptions. An experimental campaign is conducted to validate the
proposed setup by producing a SAR image of the environment captured using a UAV
flying with a Software-Defined Radio (SDR) as a payload.
