Description

technical field [0001] The invention belongs to the technical field of electronic measurement. In particular, it relates to a radar ranging system. Background technique [0002] At present, there are various radar ranging products on the market. FMCW is frequency-modulated wave radar. Frequency-modulated wave radar ranging is different from conventional pulse wave radar. Most of them use digital signal analysis such as Fourier transform, wavelet analysis, and instantaneous autocorrelation algorithm. method implementation. The advantage is that the circuit structure is simple and clear, and the scheme is relatively mature; the disadvantage is that the calculation amount is large, which requires high computing power of the processor. At the same time, the calculation amount will affect the power consumption of the chip, and the time accuracy and amplitude accuracy of signal sampling are high. , the cost is also higher. There are also some products that use program-controlle...
