There is a function called quadraticInterpLog2ShortPeakLoc which performs a quadractic peak interpolation to compute the fractional offset of the peak location, it is called as belows:
interpOffset = quadraticInterpLog2ShortPeakLoc(obj->cfarDetObjIndexBuf, obj->numDopplerBins, detIdx1, (CFARTHRESHOLD_N_BIT_FRAC + obj->log2numVirtAnt));
Here, obj->cfarDetObjIndexBuf is an doppler index array, is there any error in invking this function? Whether obj->sumAbs should supersede it? And should the detIdx1 be repalced by obj->cfarDetObjIndexBuf[detIdx1]?Is that right?
I will have to check this with our algo experts . But have you validated by modifying the code and checking it yourself and what are your observations?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Raghunandan Kamath:
I have not validated,I just look at the code, and it doesn't make sense, so I want to confirm my thought.
