Abstract

In order to achieve stronger penetration and higher imaging resolution of future spaceborne radars, a radar system with lower frequency band and wider bandwidth must be designed. However, such designs will lead to an increase in the impact of the ionosphere, and traditional ionospheric research methods may no longer be applicable, and new analysis methods are urgently needed. This study conducts a detailed quantitative analysis of the performance of future spaceborne P-band ultra-wideband radar under the influence of the ionosphere. In the study, an in-depth evaluation of the expansion orders of the ionospheric assessment model, including Taylor expansion and Legendre orthogonal polynomial expansion, was carried out. Analysis shows that in the application of ultra-wideband radar, whether Taylor expansion or Legendre orthogonal polynomial expansion is used, the existing third-order coefficient expansion method cannot meet the accuracy requirements of ionospheric impact assessment. Correspondingly, the Taylor expansion needs to be extended to fifth-order terms, and the Legendre orthogonal polynomial expansion needs to be extended to fourth-order terms. In addition, through the fitting analysis of the point target diffusion model under the influence of the ionosphere, the quantitative relationship between the radar resolution of the P-band ultra-wideband radar and various ionospheric parameters was clarified. The results of this study can provide relevant reference basis for future high-performance radar design.
