enables us to carefully select and configure the com-
ponents in the receiving and transmitting paths, ensur-
ing efficient signal generation and accurate data cap-
ture. Moreover, the successful implementation of the
designed compact RF signal generation and data cap-
ture on an FPGA, using high-speed data converters,
showcases the practicality and feasibility of the pro-
posed design.
This work provides valuable insights and practi-
cal solutions for designing and implementing UWB
direct RF sampling transceivers, making it a valuable
resource for radar technology researchers and engi-
neers. Future research should focus on integrating
hardware implementation of the signal generation and
data capture part with the designed analog front-end
for testing and validating the design.
