1. An advanced communication apparatus in a wireless communication system, the advanced communication apparatus comprising:
a processor;
a three-dimensional (3D) imaging sensor operably connected to the processor, the 3D imaging sensor comprising an analog circuit and a digital circuit configured to:
generate a digital waveform with a polyphase coding based on a multi-input multi-output (MIMO) and orthogonal frequency division multiplexing (OFDM) processing,
process the digital waveform with beamforming in Azimuth, and
modulate the processed digital waveform using a predetermined modulation function to generate a first signal; and
a transceiver operably connected to the digital circuit and the processor, the transceiver configured to:
transmit, to a target object via a transmit antenna comprising at least one one-dimensional (1D) linear array in Azimuth, the first signal, and
receive a second signal via a receive antenna that is constructed from one or more 1D arrays in elevation, wherein the second signal is reflected or backscattered from the target object.
