Abstract：In view of the problem that the performance of the traditional corner reflector is strongly depend-ent on the incident wavelength which makes it difficult to avoid the detection of frequency conversion ra-dar,this paper designs a new corner reflector loaded with meta-material wave-absorbing layer,which cre-ates approximately the same backward radar cross sections respectively at frequency points of 8 GHz , 1 1.5 GHz and 12 GHz.The test on the performance of the corner reflector shows that after the loading meta-materials absorbing layer is processed,the RCS value is decreased by about 2 dBsm at 1 1.5 GHz and decreased by about 3.6 dBsm at 12 GHz,and its RCS curve and the value of the common corner reflector are almost the same at 8 GHz.With no significant difference between the RCS curves of two frequency points,the performance of the new corner reflector meets the design requirements,thus providing a new approach for the countermeasure against the detection and identification of frequency conversion radar which works at the X band wave (8~12 GHz)to the corner reflector false target.
