Transmitter noise considerations in super-Nyquist FMCW radar design

A design consideration for super-Nyquist frequency modulated continuous-wave (FMCW) radar systems relating to transmitter to receiver noise leakage is introduced. Phase noise curves comparing the fundamental direct digital synthesisers frequency and its second super-Nyquist image show a significant...
