它有着怪异的夹角(令人回忆起隐形轰炸机)，以减小雷达横截面，并且涂抹了雷达吸波材料。
It has odd angles (reminiscent of a stealth bomber) to reduce its radar cross-section, and was coated in radar-absorbing material.
隐形飞机依赖其外形来逃避雷达，这种外形能避免雷达波从机体资源上反射信号、且含有能吸收雷达能量的物质。
Stealth aircraft rely on shapes that prevent radar waves from bouncing back to their sources and on materials that absorb radar energy (stealth-plane time line).
尽管并不能完全隐形，但是它的外形和能够吸收雷达波的外衣使它很难被发现。
While not completely invisible to radar, its shape and radar-absorbent coating made detection extremely difficult.
