【摘要】：微波輻射計是被動遙感儀器,對人體無害,這使其對人體輻射信息成像具有很大的優(yōu)勢。全極化微波輻射計可以通過測量目標的4個Stokes參數(shù)得到目標的全部極化信息,這對人體亮度溫度分布的測量和分析是一種有效的補充,使全極化輻射計在醫(yī)學方面的應(yīng)用成為可能�；谏衔粰C軟件控制的二維掃描平臺,設(shè)計出一套軟件控制與成像方法,控制全極化輻射計對目標進行平面掃描,得到目標的輻射亮溫圖像。使用37GHz的全極化輻射計進行在近場條件下的人體掃描成像實驗,得到了T_v、T_h、T_3、T_44個通道的人體量溫圖像,驗證了全極化微波輻射計掃描人體成像方案的可行性。
[Abstract]:Microwave radiometer is a passive remote sensing instrument, which is harmless to human body, which makes it have a great advantage in imaging human body radiation information. Full polarization microwave radiometer can obtain all polarimetric information of the target by measuring four Stokes parameters of the target. This is an effective supplement to the measurement and analysis of the luminance and temperature distribution of the human body, and makes possible the application of the fully polarized radiometer in medicine. Based on the two-dimensional scanning platform controlled by the upper computer software, a set of software control and imaging methods are designed. The target radiation bright temperature image is obtained by controlling the full polarization radiometer to scan the target. The human body scanning imaging experiment under near-field condition is carried out by using the full-polarization radiometer at 37GHz. The human body mass temperature image of Tvsp Th _ T _ T _ 3O _ T _ 44 channels has been obtained by using the Tvsp _ T _ T _ T _ T _ 3T _ T _ 4 channel. The feasibility of the full polarization microwave radiometer scanning human body imaging scheme is verified.
