| description | The invention relates to an in-field scene construction method based on a measured data characteristic model, belongs to the technical field of electromagnetic scene simulation, and solves the technical problems of echo characteristic distortion and poor target polarization characteristic simulation fidelity of in-field electromagnetic scene simulation in the prior art. The method comprises the following steps: establishing a plurality of external field test scenes, and obtaining actually measured radar target echo data in each external field test scene; generating a target characteristic library and a background noise library based on actually measured radar target echo data in each external field test scene; according to scene setting requirements of an infield scene, selecting a target scattering characteristic model from the target characteristic library, and selecting background noise data from the background noise library; and in the infield scene, according to scene setting requirements and the called |
