Radar cross-section (RCS) analysis of high frequency surface wave radar targets
نویسندگان
چکیده
Realistic high frequency surface wave radar (HFSWR) targets are investigated numerically in terms of electromagnetic wave – target interactions. Radar cross sections (RCS) of these targets are simulated via both the finite-difference time-domain (FDTD) method and the Method of Moments (MoM). The virtual RCS prediction tool that was introduced in previous work is used for these investigations. The virtual tool automatically creates the discrete FDTD model of the target under investigation and performs the FDTD RCS analysis. It also automatically constructs a MoM wire grid model of the target; therefore, it is also possible to compare FDTD results against the MoM-based NEC (Numerical Electromagnetic Code) data. Bi-static RCS patterns under a variety of illuminations over the whole HF band (3-30 MHz) are presented. The mono-static RCS vs. frequency of these targets is also given.

In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...

The Radar Cross Section of a target plays an important role in the detection of targets by radars. This paper presents a new method to predict the bistatic and monostatic RCS of coated electrically large objects. The bodies can be covered by lossy electric and/or magnetic Radar Absorbing Materials (RAMs). These materials can be approximated by the Fresnel reflection coefficients. The pro...
