    Abstract

    When the flight velocity of a target is more than 5 Ma, its radiation peak wavelength falls within the range of shortwave infrared (SWIR), and with the distinctive characteristics such as stronger in radiated power and varying fast with time, it is easy to be detected by the SWIR sensor. SWIR detector transduces the incident photons of the target reflected by atmospheric particles into electrical signals. Through monitoring the amplitude change of electrical signals, a strong radiation source approaching can be estimated, and then the early warning time can be advanced.
