Abstract

The invention provides a radar target electromagnetic scattering characteristic simulation method and device. The method comprises the following steps: establishing a group target electromagnetic calculation model according to the geometric dimension, the state and the initial relative position of each sub-target in a group target; dividing each sub-target into different components of the group target, respectively setting motion characteristics of each component, and calculating positions and states of the group target at different moments; and adopting a high-frequency progressive method to simulate and obtain dynamic electromagnetic scattering characteristic data of the group target according to the positions and states of the group targets at different moments. The device comprises a modeling module, a component division module and a calculation module.

Description

technical field [0001] The invention relates to the research field of electromagnetic scattering characteristics of radar targets, in particular to the simulation technology of electromagnetic scattering characteristics of group targets. Background technique [0002] As the form of war accelerates towards intelligent evolution, group operations will become an important form of future operations, and the identification of group targets (such as ballistic targets and drone groups, etc.) also puts forward new requirements for radar systems. Radar target recognition refers to the technology of using radar to detect a single target or a group of targets, and analyzing the acquired information to determine the type, model and other attributes of the target. To obtain the scattering characteristics of radar targets, there are currently two main approaches: off-site actual measurement and theoretical modeling and simulation calculations. Off-site actual measurement is costly and ti...
