Abstract: Disclosed is a sign apparatus for displaying a sign for traffic or a vehicle, where the sign apparatus includes a display configured to display the sign and to permit a radar signal radiated from a source to pass, a filter configured to attenuate a signal of at least one frequency in the radar signal passing through the display and to allow a signal of a remaining frequency to pass, and a reflector configured to reflect the signal passing through the filter, wherein the reflected signal includes encoded identification information of the sign.

Abstract: A method and apparatus with radar signal processing are included. A method includes transmitting, through transmission antenna elements, a radar signal at a transmission time interval corresponding to a time division multiplexing (TDM) latency, receiving a reflected signal of the radar signal through reception antenna elements, determining directions of arrival (DOAs) respectively corresponding to the transmission antenna elements by classifying radar data corresponding to the reflected signal, wherein the classifying is based on the transmission time interval, determining an unambiguous element of a phase error element by applying an ambiguous Doppler velocity that is based on the radar data to the phase error element of the individual DOA data, and determining integrated DOA data corresponding to the transmission antenna elements by integrating the individual DOA data by suppressing an ambiguous element of the phase error element.
