Abstract:
A 3-D path detection system includes an image capture device, a radar device and a computing module. The image capture device is provided to produce a dynamic image for calculating the x- and y-direction (transverse) pixel-value displacements according to a captured moving object image. The radar device is configured to transmit an input wireless signal to a moving object and receive a reflection signal from the moving object, and is configured to calculate a z-direction (longitudinal) displacement of the moving object according to a Doppler shift in the reflection signal. The computing module is configured to construct a 3-D path of the moving object according to the x- and y-direction pixel-value displacements of the moving object image and the z-direction displacement of the moving object.

Claim (Index 5):
The 3-D path detection system in accordance with  claim 4 , wherein the radar device includes a coupler, an antenna, an injection-locked oscillator (ILO), an amplifier and a demodulation circuit, wherein the coupler is configured to receive and couple the input wireless signal to the antenna and the ILO, allowing the ILO to operate in an injection-locked state and output a lock-in signal, wherein the antenna is configured to transmit the input wireless signal to the moving object and receive a reflection signal from the moving object, wherein the coupler is then configured to receive and couple the reflection signal to the amplifier, and wherein the demodulation circuit is coupled to the ILO and the amplifier and is configured to quadrature demodulate an amplified RF signal output from the amplifier using the lock-in signal output from the ILO.
