January6, 2007: Of great interest to American intelligence reconnaissance units (that operate aircraft and ships loaded with electronic monitoring gear) is the Chinese efforts to develop the ability to detect stealth aircraft. American stealth aircraft rely on materials and design factors that confuse radar and heat sensing systems. Chinese spies have shown an intense interest in American stealth technology, and part of that is the need to know exactly how it works. With that knowledge, it is possible to tweak your radars and other sensors to make American stealth aircraft less stealthy. It is believed that the Chinese are already adjusting some of their radars, and deploying new electronic sensors, in an effort to defeat stealth. China is working on a system that will use radars on ships, land and in the air to, in combination, make U.S. stealth technology less so. Thus the intense interest U.S. electronic monitoring units have in what the Chinese military is broadcasting these days.
