ØTo generate linear and non-linear FMCW signal
ØTo analyze and compare the detected results of the target range, velocity and angle under linear and non-linear FMCW signal
- SystemVue Automotive Radar can generate non-linear FMCW chirp for system performance analysis.
- Experiments show the non-linear FMCW significantly affects the AOA detection, as well as range detection. The most significant impact on AOA, less impact on velocity detection.
- Some DSP approaches could decrease the non-linear impact, for example, remove (chop) the serious non-linear part of the frequency-up/down time area, use the part with better linearity.
