| Abstract: | The target detection model of the airborne radar which refers to the single pass gain coefficient and backscattering coefficient was established. A corresponding guide line of airborne radar was given. Based on the simulation, the earth curvature's influence to target echo and surface clutter power was analyzed quantitatively. The simulation results show that the structure and mathematical expression are effective and reliable. |
