Summary:
A pulse radar front-end using an NRD-guide technology was fabricated as a radar system for a millimeter wave level sensor, and then range finding was performed by using it. Multi-reflection however occurred between a target and a planar antenna due to a pencil beam radiation of our developing planar antenna, so that a precise distance could not be calculated for short range detection. In this paper, an FPGA-based signal processor was devised in order to eliminate such multi-reflection, and experimental errors of less than 30 cm could be achieved for the distance range from 2 m to 20 m under the multi-reflection environment.
