Ripple Metrics (Advanced Radar)
Menu Path:
This topic describes the Ripple metrics displayed in the Pulse Table.
-
Ripple (dB) --Reports the amplitude level ripple, per pulse, as dB. This metric is measured over the specified Ripple Analysis Width (%).
-
Ripple (%) -- The maximum difference between the waveform and the On Line while in the on position, divided by Range.
-
When Amplitude Scaling is set to Real, the Ripple (%) metric is reported in %V units.
-
When Amplitude Scaling is set to Magnitude, the Ripple (%) metric is reported in %W units.
-
The Ripple measurement interval is determined by the user-specified Ripple analysis offset From Pulse Top Start and offset From Pulse Top End properties.
Ripple is calculated as the measured difference between the maximum and minimum amplitude deviation points from the ideal droop compensated pulse top amplitude reference line.
For a pulse signal containing no measured droop, the values L_top+ = L_top- = L_100%, and the above formulas reduce to:
The following image shows the levels used in the above calculations.
