Abstract:
|
The design of a 94 GHz Total Power Radiometer
system for imaging purposes is presented in this paper. A mechanical beam-scanning antenna system is used to acquire
passive raster images. The main performance parameters of the imaging system are described as well as their impact on the
resulting image quality. A temperature resolution below 1K and a spatial resolution around 4 cm at 1 meter standoff distance are
obtained with this system. Moreover, radiometric images acquired in indoor and outdoor environments are shown and
compared. |
