Analysis on ultra-wideband scattering characteristics of complex missile with empennages

In order to meet the requirement for measurement and detection of complex missile targets, a complex missile model with empennages is established and its scattering characteristics are studied under the conditions of the missile irradiated by extremely short pulse. Transient scattering echoes of the missile model are calculated using Finite-Difference Time Domain (FDTD) algorithm. The characteristics of the missile scattering echoes are analyzed at different incident angle conditions in far field and at different rotational angle of the missile in near field. These analyses on the scattering echo characteristics reveal the causes of the missile scattering centers and characteristics of scattering waveforms, which can provide theoretical reference in radar application.
