Interpolation Process - Safran CORTEX CRT Quantum User Manual

3.3.4.3. Interpolation Process

In some cases, when the sampling rate and the generation rate are asynchronous, a linear interpolation is
applied to provide the accumulated phases at the required sampling frequency.
Such an interpolation generates an error. Let's call
��
10-ms period and the time between 0 and T when the phase is interpolated.
The Taylor expression of the phase at
where D(t) is the input Doppler and R2(t) the rest such that (Lagrange overestimation):
��
������
So
For instance, a Doppler rate of 1000 Hz/s with a second-order Doppler variation of 10 Hz.s
lower than (0.0125 + 3.33x10
In most cases, user would not use cranky values for the sampling rate. Thus, no interpolation would be applied,
because accumulated phase is generated synchronously with the sampling rate dates.
