摘要： 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.
