Example Embodiment
[0049] For the foregoing and other technical contents, features and effects of the present invention, please refer to the attachment below figure 1 Attached Figure 5 It will be clearly presented in the detailed description of the embodiments. The structural content mentioned in the following embodiments are all referenced to the drawings in the specification.
[0050] Such as figure 1 As shown, the ranging equipment based on FMCW radar signal processing includes radar, signal processing module and processor. The radar selects the integrated transceiver chip of model BGT24MTR11. The internal transmitter and mixer of BGT24MTR11 can realize the conversion of radar transceiver. Function, the processor uses ST's STM32F407 chip. The STM32F407 chip comes with a 12-bit A / D converter. Due to the A / D sampling rate configuration problem of the STM32F407, the product takes the A / D sampling rate of 72.19KHz.
[0051] Such as figure 2 As shown, the signal processing module includes a filter...
