2.11.6 Notes

[1] P1, P2 and P3 amplitudes are derived by averaging all samples within 3dB of the maximum pulse amplitude. P1A amplitudes are averaged over the whole calibration window length in the current PF-ASAR implementation. In reality P1A pulse levels are significantly above the noise floor and therefore the amplitude averaging should be performed as for the other three calibration pulse types.
