Distributed synthetic aperture microwave radiometric high-resolution imaging algorithm based on data fusion

In view of the problem that both the antenna array and system complexity of large distributed synthetic microwave radiometer system increase with the improvement of imaging resolution, an imaging algorithm based on data fusion for synthetic aperture microwave radiometer with high-resolution is proposed. Firstly, the data fusion model is established. And then the data fusion algorithm is discussed in detail. Finally, a series of ground validation imaging tests are carried out and some imaging results are presented. Both the theoretical and experimental results demonstrate that the proposed algorithm is feasible and can effectively improve the imaging resolution. Moreover, it provides a new solution for enhancing the spatial resolution of microwave radiometric remote sensing from the perspective of data dimension.
