Abstract :
In this paper, it is analyzed numerically the normalized RCS (NRCS) of partially convex conducting targets of large sizes of about five wavelengths in continuous random media. Here, we assume that waves around target are incoherent and the SLC keeps a finite value. In this work, we considered the case when the incident wave illuminates the convex portion of a concave-convex target. Here, it is analyzed numerically the ERCS in three regions of ka compared to SCL. For ka << SCL, NRCS equals two due to the double passage effect on waves in random media. As a result, it is concluded that in the regions ka << SCL and ka >> SCL, the ERCS is almost due to the double passage effect; and in between these two regions ERCS deviates from two depending on the SCL.
