Abstract
A high fidelity wideband radar signature prediction model for space objects with precession is developed, where the micro-motion model, electromagnetic scattering calculation and linear frequency modulated (LFM) radar signal model are integrated. The fidelity of the model is demonstrated by comparing both the radar cross section (RCS) and high-resolution range profile time sequences with anechoic chamber measured data. Wideband LFM radar returns of dynamic space object are simulated and analyzed based on the proposed model, considering the limitations of ideal point scatterers model for the precession target signature simulation and the radar imaging distortions impact of paired echoes.
