Random Phase and Dual PRF
The random phase processing works seamlessly with the dual PRF processing to provide
advanced range and velocity ambiguity resolution. Both the first and 2nd trip echoes can be
recovered and displayed to a maximum range of 2X the unambiguous range corresponding to the
high PRF.
For optimum performance, the 2D 3x3 speckle filter should be used to smooth the 2nd trip
seams that occur for each ray. In fact, this smoothing of the 2nd trip seam makes the dual PRF
random phase mode work even better than the single PRF random phase.
