The range sampling rate (RSR) is defined as:

$\displaystyle {\rm RSR} = 0.001 \frac{Np-1}{\,dt_r}$ (D39)

RSR is the range sampling rate in MHz.
Np is the number of (range) pixels.
$ \,dt_r$ is the zero Doppler two-way time to the last pixel minus the range time to the first pixel in milliseconds.
