Chaff Cloud Modeling and Electromagnetic Scattering Properties Estimation

نویسندگان

چکیده

Chaff is a radar countermeasure used to interfere with ground detection or missile target by disrupting the radar. As essential in modern electronic warfare, chaff also essentially many military vehicles. A large amount of chaffs form thin and long wire contained cylindrical rectangular cartridge launched cloud disturb It virtually impossible examine analytically because it released at once into air quantities. Therefore, for analysis, an approximation method statistical characteristics are used, real data measured directly through experiments. The study consists two parts: modeling, which determines dynamic chaff, estimation electromagnetic scattering properties, signal chaff. This review paper focuses on techniques modeling properties. We categorized statistical, numerical, empirical methods. In studies purpose analysis generally use typical distribution, whereas if itself purpose, aimed realizing realistic referring experimental data. For conventional that simply multiplies average cross-section element obtain total allows rapid calculation while considering distribution being studied.

Electromagnetic Scattering from Grassland—Part II: Measurement and Modeling Results

The validity of a coherent, grassland scattering model is determined by comparing the model predictions with direct measurements of a representative grass canopy. A wheat field was selected as the test target, and polarimetric, multifrequency backscattering data were collected over an entire growing season, along with a complete set of ground-truth data. The L-band measured data demonstrated a ...

Visualization of Chaff Cloud Aerodynamics based on Random Generation of Chaff Dipoles in 3D Space

Chaff is one of the most widely used and effective expendable electronic attack (EA) devices. It is a form of volumetric radar clutter consisting of multiple metalized radar reflectors known as chaff fibers designed to confuse hostile radar operation. It is dispensed into the atmosphere to deny radar acquisition, generate false targets. To understand the dynamics of chaff cloud, a software has ...

Low-Frequency Electromagnetic Scattering

The main result of this paper is to reduce the calculation of higher-order terms in the asymptotic expansions of the electric and magnetic elds at low frequencies to the solutions of certain canonical problems. We also provide a new and simple variational proof of the convergence of the electric and magnetic elds solutions of the scattering problem for the Maxwell equations as the frequency goe...

Electromagnetic scattering from anorthotropic

We investigate electromagnetic wave propagation in an inhomogeneous anisotropic medium. For the case of an orthotropic medium we derive the Lippmann-Schwinger equation, which is equivalent to a system of strongly singular integral equations. Uniqueness and existence of a solution is shown and we examine the regularity of the solution by means of integral equations. We prove the innnite Fr echet...
