Study to improve the landform adaptability of radar super-resolution algorithm

It is found that super-resolution algorithm is influenced seriously by landform in the course of usage. The reason is that the reflection echo model is not matched to the true signal radiate path. The raytracing method is adopted to make the model more close to the true signal radiate path, and the landform adaptability of super-resolution algorithm is improved. Results of emulation and experiment data show that this algorithm is very effective in improving the landform adaptability of super-resolution algorithm. The proposed algorithm is also affected by landform. The angle measurement precision becomes lower while the hypsography becomes worse.
