Fast Calculation of Multi-Target RCS

The electromagnetic scattering feature is an important performance index of flying targets, which is of great significance for the stealth performance of own targets and the detection of enemy targets. In order to solve the calculation problem of the multi-target radar cross section (RCS) in formation flying, the fast calculation method of multi-target RCS is studied. The traditional radiation pattern product method is improved, combined with the shooting and bouncing ray (SBR) method, and a method suitable for calculating multi-target RCS is proposed, which can obtain the total scattered field and RCS of uniform linear targets or uniform planar targets with a small amount of calculation. Compared with the RCS calculated by the traditional SBR method, the calculation amount is reduced under the premise of ensuring the accuracy.
