    Abstract: A radar system transmits pulses towards a target and receives pulses reflected back therefrom. Based on samples (of the received pulses) corresponding to a CPI, a first 2D matrix having a slow-time index and a fast-time index is generated. A slow-time FFT is performed to convert the slow-time index to a Doppler bin index to produce a second 2D matrix having the Doppler bin index and the fast-time index. Thereafter, a 1D interpolation is performed along the Doppler bin index to produce a third 2D matrix having a Velocity bin index and the fast-time index. Thereafter, a fast-time FFT is performed to convert the fast-time index to a Range bin index to produce a fourth 2D matrix having the Velocity bin index and a Range bin index. A distance to and a velocity of a target is determined based on the fourth 2D matrix.

    Abstract: Embodiments of this disclosure provide a system and method for wireless communication and wireless sensing in a low-cost common transceiver structure. In particular, the common transceiver structure may have a common digital-to-analog converter (DAC) configured to convert a digital wireless communication signal and a digital wireless sensing signal into an analog wireless communication signal and an analog wireless sensing signal, respectively. The common transceiver may also have a common transmitting antenna configured to transmit the analog wireless communication signal and the analog wireless sensing signal.
