Digital Wave Radar is Wavetronix’ patented process for digitally generating a radar signal. For proper and stable operation, frequency modulated continuous wave (FMCW) radars must transmit a stable and preferably linear frequency sweep. Any nonlinearities of the sweep can reduce range resolution. Further, changes in the df/dt sweep slope due to temperature drift may reduce the accuracy of ranges measured, and shifts in the center frequency due to temperature changes can push the transmission signal out of the FCC allocated band.
HD Digital Wave Radar digitally synthesizes the radar transmit signal such that at all times it is derived to be some numerical multiple of a fixed low crystal-controlled reference frequency.
