Abstract: Provided is a radar device and a rear seat detection method thereof, in which the method includes: (a) transmitting a radar signal in a form of a multi-channel high-speed FMCW to a periphery of the rear seat and receiving a signal reflected from a target by a transceiver; (b) detecting a motion of the passenger through a macro speed detection scheme by a signal processor; (c) detecting a change according to characteristics of the passenger through a micro speed detection scheme; and (d) determining, by a passenger detector, that the passenger is present on the rear seat when the motion or the change is detected in step (b) or step (c). Accordingly, a multi-channel high-speed FMCW radar waveform is employed to simultaneously detect the motion of the passenger detected through the macro speed detection scheme and a change caused by respiration of the passenger detected through the micro speed detection scheme, so that the passenger in the rear seat is accurately detected.

Abstract: A water quality purification system for a hybrid artificial wetland includes a first aerobic artificial wetland, an anaerobic artificial wetland, and a second aerobic artificial wetland. Here, the first aerobic artificial wetland induces a vertical flow of water, which is to be purified, and allows pollutants to be removed. The anaerobic artificial wetland induces a horizontal flow of treated water which is introduced from the first aerobic artificial wetland, and allows pollutants to be further removed. Additionally, the second aerobic artificial wetland induces a vertical flow of treated water which is introduced from the anaerobic artificial wetland, and allows air to be supplied inwardly such that the amount of dissolved oxygen of the introduced treated water increases.
