  • Parking space status sensing system and method
    Patent number: 10082566
    Abstract: A parking space status sensing system is used for detecting a state of a parking space. A parking space status sensing system includes a first antenna array transmitting a first signal, a second antenna array receiving a second signal feedback reflected from an object, a radio-frequency transceiver receiving the second signal and performing down-conversion and demodulation on the second signal with receiving a local signal modulated from a triangularly modulated signal by the radio-frequency transceiver, to generate a first beat frequency signal. An analog-distance-signal-integral information and an analog-speed-signal-integral information of the object are obtained from the first beat frequency signal by related analog signal processes.
