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 7):
The 3-D path detection system in accordance with  claim 5 , wherein the demodulation circuit includes a quadrature power splitter, a power splitter, a first mixer, a second mixer, a first low-pass filter and a second low-pass filter, wherein the quadrature power splitter is coupled to the ILO for receiving the lock-in signal and is configured to output an in-phase local oscillation signal and a quadrature local oscillation signal, wherein the power splitter is coupled to the amplifier for receiving the amplified RF signal and is configured to split the amplified RF signal into two paths, wherein the first mixer is configured to receive and mix the in-phase local oscillation signal and the amplified RF signal in one path, and the second mixer is configured to receive and mix the quadrature local oscillation signal and the amplified RF signal in the other path, wherein the first low-pass filter is configured to receive and filter a first mixer output signal from the first mixer to obtain the in-phase signal, and the second low-pass filter is configured to receive and filter a second mixer output signal from the second mixer to obtain the quadrature signal.
