Experiments on detecting ground targets with 360 GHz radiometer

In order to verify the feasibility of submillimeter wave radiometer in the terminal guidance, the sky brightness temperature and apparent temperature are calculated. Moreover, the experiments for detecting ground metal and coating stealth targets are carried out. The calculations and experiments show that the radiometer can detect ground metal targets in the cold weather and can not detect it with increasing temperature and humidity. Nevertheless, the radiometer can detect high-temperature coating stealth targets regardless of the weather.
