Study on Inlet Chamber in Aircraft Head-on RCS Simulation

In this paper, a modeling method is proposed for the most important strong scattering center of the head-on cavity component, and different algorithms are emploved to analyze the difference between the head-on RCS containing the inlet cavity structure and the actual dynamic test results of the aircraft. Through consistency comparison and difference correlation analysis derive from simulation and measurement, the modeling method including the head RCS simulation of the inlet cavity component is calibrated. The effectiveness about simulation calculation and the accuracy of model expression of the modeling processing method of the inlet cavity component.
