Fractional OAM Vortex SAR Imaging Based on Chirp Scaling Algorithm
View through CrossRef
AbstractVortex electromagnetic wave carries orbital angular momentum. Combined with Doppler information provided by radar platform movement, vortex electromagnetic wave can achieve higher resolution target imaging in SAR Imaging technology. In this paper, fractional order OAM vortex SAR imaging is studied. Firstly, the side‐looking strip SAR imaging model is established. Then, the scattering echo equation of fractional order OAM is derived. Finally, the imaging simulation of multi‐point target and single point target under Gaussian SNR is carried out by Chirp Scaling algorithm. The experimental results show that compared with the integer order OAM Vortex SAR Imaging, the fractional order OAM Vortex SAR Imaging in this paper has stronger robustness in Multi‐target and Noise environment, which proves the effectiveness of the fractional order Vortex SAR Imaging.
