An apparatus and method for identifying a human being and an animal are disclosed to properly identifying whether or not a target is a human being or an animal. The apparatus for distinguishing between a human being and an animal includes: a target stimulation unit generating a stimulation signals for selectively stimulating the senses of a human being and an animal and providing the generated stimulation signal to a target; and a target identifying unit detecting the reaction of a target to the simulation signal to identify whether or not the target is a human being or an animal.

Apparatus and method for distinguishing between human being and animal using selective stimuli

A pulse radar receiver includes a power splitter configured to split a transmit (TX) trigger signal for generating a TX pulse, a phase-locked loop (PLL) configured to receive a division ratio and the TX trigger signal split by the power splitter, and generate a sampling frequency, and a sampler configured to sample a reflected wave received through an RX antenna, according to the sampling frequency generated by the PLL. Accordingly, it is possible to provide a high distance resolution by generating a sampling frequency with a difference from a TX pulse to sample a reflected wave received through an RX antenna. Thus, it is possible to overcome a limitation in the distance resolution due to the pulse width and to measure a minute movement at a short distance. Therefore, the pulse radar receiver is applicable to high range resolution radar applications such as a living body measuring radar.

Pulse radar receiver

Disclosed is a pulse-signal recovering device with a time-interleaving scheme. Exemplary embodiments of the present invention can improve receive performance of a radar so as to shorten pre-scanning time for roughly determining presence and absence of objects and time consumed to recover received pulse signals in the radar receiver with the sub-sampling scheme by simultaneously sensing signal levels of the received pulse signals at several positions and improve a signal to noise ratio by increasing an averaging rate with respect to the number of same received pulses.
