Other AbstractThrough the airborne experiment,a research on the W2band Millimeter Wave Radiometer (RADW92) is introduced in this article.Microwave remote sensing images of parts of the Yellow River and the Weihe River were acquired,which were the first batch images produced from scanning W2band Millimeter Wave Radiometer in China.The experiment shows that RADW92 is adequate for space use. The analysis of some factors influencing the image quality as well as the solutions to them are included in this article.The RADW92 works with operating frequency at 92GHz,the bandwidth 2GHz,the integration time 60ms,the system sensitivity 0.6Kand the linearity better than 0.999.Cassegrain Antenna was designed for conical scanning and imaging.   The two images presented in the paper are both original results without any correction.Compared to the reference map,both rivers on the images have the identical trends with the reference maps.The geometrical formof both rivers has distortion to some extent.Many reasons can result in the distortion including scanning track approximation ,longitude and latitude approximation,altitude error,velocity and attitude approximation,etc.Moreover,the algorithmof software is also an important factor that affects image qualities.According to that,the observed data for spaceborne imaging should be matched with the parameters of the imaging platform for the geometrical correction.
