This paper is an important part of Native Defense scientific research fund task "the control technology for MMW radiation characters of amphibian tanks". We mainly study the radiation characters of stealth objects.First, this paper discusses the modeling of objects' radiation characters and the measuring principle of MMW radiometer. Then emulates the interaction between the antenna temperature and the brightness temperature which devotes the objects radiation characters with BP neural network, and retrives the brightness temperature from the measured antenna temperature. In addition discusses other inversion algorithm of retrieving the brightness temperature including the gradient method, the DFP method and the extremum method. And these inversion algorithms are checked in the experiments. At last, analyses the stealth principles to radiometer of 3mm coating stealth material and provides a method to estimate the stealth effect.
