Radar apparatus and method of detecting target object |
摘要 |
This disclosure provides a radar apparatus, which includes an antenna for discharging a transmission beam with frequencies corresponding to elevation/depression angles with respect to a particular surface and receiving a reflection echo from a reflective body and a reception module for detecting an elevation/depression angle of the reflective body based on a frequency component of a reception signal received by the antenna and detecting a distance of the reflective body based on a time component of the reception signal. |

1. A radar apparatus, comprising:
an antenna configured to discharge a transmission beam with frequencies corresponding to elevation/depression angles with respect to a particular surface, the antenna discharging the transmission beam at various azimuths while rotating around a rotational shaft perpendicular to the particular surface, and further configured to receive a reflection echo from a reflective body; a receiver configured to detect an elevation/depression angle of the reflective body based on a frequency component of a reception signal received by the antenna and detect a distance of the reflective body based on a time component of the reception signal; a reference surface discriminator configured to discriminate a reference surface from among the reflective bodies based on azimuth, distance and elevation/depression angle information of the reflective bodies; and a target object discriminator configured to discriminate a target object from among the reflective bodies by extracting, based on azimuth, distance and elevation/depression angle information of the reflective bodies, reflective bodies that are located above the reference surface. |
