2.8 Range-Doppler Dilemma
The physical relationship between the unambiguous range and unambiguous velocity limits the dynamics
of the acquired data. An example is shown in the diagram below. The unambiguous velocity can be
increased with the staggered PRF algorithm. The unambiguous range can be increased by reducing the
PRF (This also reduces the unambiguous velocity)
