An Improved Fusion Scheme for Multichannel Radar Forward-Looking Imaging

To achieve high-quality forward-looking imaging of multi-channel radar, the fusion of synthetic aperture imaging result and real aperture superresolution result is usually necessary. However, the fusion processing by directly multiplying two results will seriously affect the image quality. In this paper, based on the analysis of the characteristics of synthetic aperture imaging results and super-resolution results, the logarithm transformation is introduced firstly on the synthetic aperture result before multiplication fusion processing to improve the image quality. Simulation results are illustrated to verify the effectiveness of the proposed scheme.
