# Image Dehazing Enhancement Strategy Based on Polarization Detection of Space Targets
## 7 Conclusions  
The technology of polarization detection has the advantage of identifying targets through clouds and fog, but due to the long detection distance of space targets and the imaging conditions of dark and weak, the advantages cannot be exploited in the polarization detection system of space targets. In order to solve the above problem and improve the detection ability of the system under complex conditions, an image dehazing enhancement strategy is proposed in our paper.  
Firstly, to improve the accuracy of solving the polarization information of the image before dehazing, the Hybrid Multi-channel Interpolation method based on Regional Correlation Analysis (HMIRCA) is proposed, and the comparative results show that the pseudo-polarization edge caused by the instantaneous field of view error can be suppressed more effectively than other methods, so as to improve the image quality of the preprocessing process. Secondly, the image dehazing method based on full polarization information inversion is proposed to restore the polarization information of space targets to the greatest extent. Thirdly, to enhance the dehazing effect of the image and improve the contrast, the fusion method based on Discrete Cosine Transform (DCT) and Local Spatial Frequency (LSF) is proposed to fuse the dehazing intensity image and the polarization image of space targets obtained by inversion. Finally, the effectiveness and feasibility of the proposed image processing strategy are verified by polarization detection experiments of simulated space targets and real space targets. The verification results show that the contrast of targets in images can be improved, and the quality of polarization dehazing images can be significantly enhanced, thereby improving the detection ability of the space target detection system under complex conditions.  
Our research results have important practical significance for improving the performance of space target polarization detection systems. In future work, larger aperture telescopes can be used to obtain higher resolution polarization images of space targets, and based on the large number of measured images obtained, the adaptability of the method proposed in this paper can be improved, thereby, the application of the polarization detection technology of space targets can also be promoted.
