The problem of the dipole cloud is an effective scattering cross-section while observed by a monostatic radar was studied.

The radar cross-section was further reduced because the wings' leading and trailing edges were composed of nonmetallic honeycomb structures that do not reflect radar rays.

由于机翼和尾部边缘的蜂窝状非金属结构不反射雷达波，所以飞机的雷达反射波就减少了很多。

It differs from stealth technology, which does not make an aircraft invisible but reduces the cross-section available to radar, making it hard to track.

但它不同于隐形技术。隐形技术不是让飞机变得看不见，而只是减少能被雷达探测到的切面以使其难以被追踪到。

The discussion established that while the B-2 may occasionally be detected by some radars, its stealth technology reduces the radar cross-section of the B-2 to the point where radar tracking of the requisite continuity and accuracy is impossible.

The craft could gather intelligence data for defense purposes it has no radar cross-section and makes no noise.

Had the early problems it experienced fatal crashes, shortfalls in initial radar cross-section performance and other design problems been made public at the time, the naysayers might have succeeded in preventing the United States from having a Stealth fighter-bomber in the arsenal when it was needed.
