要約(英語): An NRD-guide pulse radar front-end was fabricated as a short range sensor at millimeter wave lengths, and the distance and velocity detections were successfully performed. A-D converters are usually used to precisely detect the target information. They however become expensive for short range applications using narrow pulse widths because they need high speed operation using sampling clocks with higher pulse repetition frequencies to satisfy the sampling theorem. To reduce the cost of the digital signal processing circuits, we applied a manner that the reflected pulse trains are easily converted into digital signals using sampling clocks with lower pulse repetition frequencies based on the sequential sampling technique which was previously-performed in the FPGA. The detection of the target information was successfully performed by the cost-effective procedure by the NRD guide pulse radar system at 60 GHz license-free band in Japan.
