probability of detection
Explanation:
probability of detection PD is the ratio of detected aims to the number of all possible blips on the radar screen, i.e. all possible targets in a given direction. The radar must detect, with greater than or equal to 80% probability at a defined range, a one square meter radar cross-section.

I fear your spurious addition of the 'eau' which does not appear in your source text has been leading you astray.
