Popis: |
In order to meet the requirements of terahertz radar for space target detection, the radar cross sections (RCS) of typical satellite targets in the lower terahertz region is studied. A typical satellite target with rough body is established by using half edge data structure. The RCS distributions at different heights, root-mean-square, correlation lengths and different frequencies are calculated by using the hybrid method of Physical Optics method (PO), Shooting and Bouncing Ray method (SBR) and Truncated-wedge Incremental-length Diffraction Coefficients (TWILDCs). The results show that RCS is more sensitive to the fluctuation of the target surface, the frequency and incident angle in terahertz band. |
