A DDS/PLL architecture for highly stable local oscillators

Low complexity portable MIMO radar system for the characterisation of complex environments at high resolution

“…A hybrid DDS–PLL architecture has been chosen to generate the main RF signal, whose frequency describes a linear sweep over a wide band. This PLL‐based generator has an extremely low phase noise and high‐frequency purity and stability and offers fine frequency tuning possibilities at a reduced cost [32–34].…”
