Vulnerabilidades del J-20 de China/ Stealthy Chinese J-20 Vulnerable

El nuevo caza de quinta generación chino, el J-20, con características furtivas, necesitará un intensivo desarrollo para enfrentarse a la creciente tecnología contra la furtividad, como los radares AESA, capaces de detectar pequeños objetos de baja observabilidad a una gran distancia.

China’s newest combat aircraft prototype, the J-20, will require an intense development program if it is going to catch up with fast-moving anti-stealth advances.
In fact, anti-stealth will bring into question all stealth designs: How much invulnerability will current low-observability techniques offer as air defense systems adopt larger and more powerful active, electronically scanned array (AESA) radars?
From the early days of AESA development, a key goal was to build a radar that could detect very small objects—such as a cruise missile at a distance great enough to target and shoot it down—or a larger object like a fighter with a very low-observable treatment.
