1. A vehicle comprising:
an ultra-wide band (UWB) transceiver configured to operate in a first mode and a second mode, wherein the UWB transceiver is configured to perform phone-as-a-key (PaaK) localization in the first mode and radar sensing in the second mode;
a memory configured to store computer-executable instructions; and
a processor configured to access the memory and execute the computer-executable instructions to:
activate the UWB transceiver in the first mode for a first predetermined time duration in a first UWB cycle;
obtain a trigger signal to switch the UWB transceiver from the first mode to the second mode for a second predetermined time duration in the first UWB cycle;
cause the UWB transceiver to transmit a radar pulse signal responsive to obtaining the trigger signal;
receive a radar response signal reflected from a target location inside the vehicle;
determine a sitting area profile associated with a sitting area and an occupant presence on the sitting area based on the radar response signal; and
perform sitting area adjustment based on the determination of the sitting area profile and the occupant presence.
