A consideration on velocity detection using NRD guide pulse radar at 60 GHz

An FPGA-based digital signal processing circuit to detect velocities of targets was considered for NRD guide pulse radar at 60 GHz. Because what to keep in mind is using a previously-designed digital signal processing circuit to detect distances to the targets from the radar, we add the circuit to a function to easily detect the velocities of the targets. In this paper, the digital signal processing circuit was developed to detect the velocities of the multi targets by differentiating the measured distances of those. To confirm the operation of the designed circuit, a pseudo reflection pulse train from the targets was made and inputted into the circuit. As a result, the velocities detection was successfully performed according to the theory.
