Abstract:

Coating the strong scattering region of target surface with radar absorbing material (RAM) is one of the effective methods for radar cross section (RCS) reduction. A definition of strong scattering regions based on shooting and bouncing rays (SBR) is given: judging a strong scattering region based on the included angle between outgoing direction of rays and receiving direction of radar. The RCS reduction characteristic of complex target’s strong scattering region coating RAM is analyzed, and the size of the strong scattering region and the RCS reduction effects with different judging included angles are studied. Calculation results show that the strong scattering region coating RAM can reduce RCS with a limited increase in weight.
