Abstract
This paper presents a direct-sampling pulsed radar
with a high-resolution digital-to-time converter ( DTC) for esti-
mating the time of flight (TOF), which is to identify the distance
between a target and radar. The implemented direct-sampling
radar can reconstruct the scanning waveforms in di gital domain.
The link budget of the radar transceivers is analyzed for the
overall scanning range. The scanning range of the radar is de-
pendent on the TOF between radar transmitter an d receiver. The
