Elie Fares,Jean-Paul Bodeveix,Mamoun FilaliIn the previous chapter our main concern was the calculation of the probability of detection of expected targets in terms of the geometry and relative configuration of targets, detectors, and control grids. The emphasis was on the maximization of detection, but no consideration was given to the cost required to achieve the set goal.作者: 螢火蟲 時間: 2025-3-26 15:11 作者: airborne 時間: 2025-3-26 18:33 作者: 左右連貫 時間: 2025-3-27 00:33
