Exploring sub-strong scattering source of canopy of fighter with radar stealth technology

Abstract

The canopy of a fighter is the main source of electromagnetic scattering, and the achievement of its radar stealth is one of key technologies for developing a stealth fighter. The scattering sources mainly include the scattering in the cavity of the canopy (strong scattering source) and the local structural scattering (sub-strong scattering source). To satisfy the high stealth requirements, it is necessary to reduce the RCS of the sub-strong scattering source of the canopy. This paper studies the sub-strong scattering source of the canopy of a stealth fighter and proposes the canopy's sub-strong scattering source reduction and control measure by applying the basic radar stealth technology, the MLFMM and the RCS test.
