摘　　要：对于优化设计和涂有吸波材料的隐身目标一般用常规雷达无法发现。提出了一种用微波辐射计来进行遥感隐身目标的探测方法,它采用测量大气热噪声方法对目标进行探测,不仅能够探测隐身目标,而且本身也具有隐身功能。通过机理和方法分析表明:用微波辐射计探测隐身目标的方法是可行的,关键是要提高微波辐射计的空间分辨率和温度分辨率。Commonly conventional radars can not discover the stealth target with optimized design and covered with microwave absorption material. We put forward a method for detecting remotely the stealth target by using a microwave radiometer. The radiometer can reconnaissance or detect the target through measurement of white noise in the atmosphere, which can not only detect the stealth target, but also is concealable itself. Analysis to its mechanism shows that it is feasible to use microwave-radiometer for detecting stealth target and also the conventional planes, but the focus is to increase spacial resolution and temperature resolution of the radiometer.
