14. A sensing vehicle (SV) performing a vehicle image reconstruction in a wireless communication system, the first terminal comprising:
a transmitting device and a receiving device; and
a processor,
wherein the processor is configured to:
receive a plurality of stepped-frequency-continuous-wave signals (SFCWs) from target vehicle (TV);
receive signature waveforms in a different frequency range for the plurality of SFCWs;
perform synchronization by using phase-difference-of-arrival (PDoA) based on the signature waveforms;
reconstruct one or more virtual images of the TV; and
derive a real image from the one of more virtual images.
