Ultrawideband radar

摘要

Radar in accordance with some embodiments of the inventive concept may include a transmission part outputting a signal to a target object; a receiving part receiving a reflected signal corresponding to the output signal of the transmission part; and a signal processing part receiving the reflected signal from the receiving part to distinguish the target object. The signal processing part directly samples the reflected signal and compares any one of the directly sampled reflected signal and a signal that the directly sampled reflected signal is restored with restored reflected signal data to distinguish the target object.

主权项

1. A radar comprising:
a receiving part receiving a signal reflected from a target object; and a signal processing part processing the reflected signal, wherein the signal processing part directly samples the reflected signal, wherein the signal processing part comprises an analog-to-digital converter directly sampling the reflected signal, and wherein the analog-to-digital converter samples the reflected signal at a first interval to generate first sampled signals having the first interval, modifies the first sampled signals to obtain second sampled signals having a second interval different from the first interval before a next reflected signal is input to the analog-to-digital converter, and quantizes the second sampled signals.
