Measurement class

Hi All,

I am attempting to create a range rate difference of arrival class. I am thinking of combining the logic from TDOA class and RangeRate class to calculate range rate difference of arrival. I would like to know if there is anything else I should specifically be mindful when calculating range rate difference ?

The TDOA class has two loops to calculate emitterPV / primePV and secondPV.
I would assume a range rate difference of arrival code would also have the similar loops to calculate the emitterPV , primePV and secondPV. Is it safe to assume that these values will be same across both classes for the same time stamp ?
