Backscattering enhancement of partially convex targets of large sizes in continuous random media for E-polarization wave

In this paper we have 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 SCL 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, we could analyze 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. For ka ≃ SCL, NRCS oscillates irregularly and obviously close to two. On the other hand, for ka > SCL, NRCS oscillates approaching to certain values that depend on the SCL. Furthermore, these values become closer to two with large SCL. As a result, we can conclude that in the regions ka ≪ SCL and ka ≫ SCL, the ERCS is almost two due to the double passage effect; and in between these two regions ERCS deviates from two depending on SCL and target configuration.
