Sampling rate 3.3.10.3
Elementary accumulated phases are sampled at the rate specified by the parameter « Doppler
measurement sampling rate » (every 100 ms to every 10 seconds, see STI). Phase generation period
depends on the sampling rate value.
If the sampling rate is a multiple of 10 ms, the accumulated phases are generated each 10 ms in order
to take advantage from raw data. Thus, Doppler measurement is based on exact values of phase.
If the sampling rate is not a multiple of 10 ms, the raw accumulated phases are sampled every 10 ms.
To obtain the accumulated phase at the desired date, an interpolation process is used. The following
figure shows how to set sampling rate for the Doppler port:
