The Chebyshev approximation technique (CAT) combined with the MoM based on electric-field integral equation (EFIE) and Poggio–Miller–Chang–Harrington–Wu–Tsai (PMCHWT) is proposed to efficiently calculate wide-band radar cross-section (RCS) passive bistatic radars (PBR). EFIE-PMCHWT equations can be used analyze electromagnetic scattering of coated targets. combination CAT only requires computin...

A fully polarimetric compact radar range operating at a center frequency of 100 GHz has been developed for obtaining radar cross section, inverse synthetic aperture radar imagery and high range resolution profiles on targets and structures of interest. The 100 GHz radar range provides scale-model RCS measurements for a variety of convenient scale factors including W-Band (1:1 scale), C-band (1:...

Sebagai negara kepulauan, Indonesia bersengketa dengan lain terkait klaim hak berdaulat di Laut Natuna Utara. Maka dari itu, diperlukan strategi pengawasan yang tepat untuk dapat mencegah dan memerangi illegal fishing Utara agar sumber daya ikan dilindungi berkelanjutan, serta tegaknya kedaulatan Indonesia. Sejak penemuannya, radar telah sangat memengaruhi semua domain peperangan militer, terma...

We describe a high-order method for computing the monostatic and bistatic radar cross section (RCS) of a class of three-dimensional targets. Our method is based on an electric field surface integral equation reformulation of the Maxwell equations. The hybrid nature of the scheme is due to approximations based on a combination of tangential and nontangential basis functions on a parametric refer...

Metamaterials with precisely chosen negative permittivity and permeability are preferable to cloak the target without scattering. In this work, a metasurface is designed by using graphene as conducting material cylinder under instancing of TM TE polarized waves in terahertz range frequencies. The electric sheet impedance magnetic admittance played crucial role achieve cloaking good scattering r...

In Modern warfare scenario, thin conducting chaff fibers with very high aspect ratio are used as passive electronic countermeasure. Radar Cross Section (RCS) of chaff cloud is an important parameter deciding its performance as electronic countermeasure. The chaff cloud is a dynamic target as when it is dispensed, it blooms in the atmosphere depending upon the atmospheric conditions and the plat...

It is well recognized that a wind turbine has a large radar cross-section (RCS) and, due to the movement of the blades, the wind turbine will generate a Doppler frequency shift. This scattering behavior may cause severe interferences on existing radar systems including static ground-based radars and spaceborne or airborne radars. To resolve this problem, efficient techniques or algorithms shoul...
