Open plasma stealth technology excited by radionuclides is known to have several problems:(1)owing to disturbance from airflow,the plasma distribution is unstable.(2)The plasma is highly dependent on the atmosphere;therefore,it is difficult to modulate in target stealth.(3)Concerns regarding radiation harassment prevent the application of this method.To avoid these problems,an enclosed plasma stealth method is introduced.Via simulation on an infinite conducting plate,this method was found to effectively solve the above concerns,which may offer a new approach for the practical application of plasma stealth technology excited by radionuclides,especially for small-satellite stealth because of its lightweight and selfprovided plasma.
