Radar Cross Section Analysis Using Physical Optics and Its Applications to Marine Targets
Radar Cross Section (RCS) is one of the most considerable parameters for ship stealth design. As modern ships are larger than their predecessors, RCS must be managed at each design stage for its reduction. For predicting RCS of ship, Radar Cross Section Analysis Program (RACSAN) based on Kirchhoff approximation in high frequency range has been developed. This program can present RCS including m...
متن کاملRadar cross-section (RCS) analysis of high frequency surface wave radar targets
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. T...
متن کاملMonopole Antenna Radar Cross Section Reduction with Plasma Helix
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 ...
متن کاملAssessment of Aircraft Radar Cross-Section for Detection Analysis
Hiding from and surprising an opponent are tactics that have been used in warfare throughout history. They were features that aircraft originally possessed when they were first used in military operations. However, development of military technology is an endless struggle between advances in technology and counter technology. During World War II this struggle led to the development of a new tec...
متن کاملRadar Cross Section Model Optimisation Using Genetic Algorithms
Many missile–target simulation systems use random numbers to mimic the effects of a fluctuating target Radar Cross Section (RCS) in an attempt to minimise simulation times. In this paper a Genetic Algorithm is used to optimise the complexity of a pointscatterer model with a realistic radar cross section, ultimately allowing real measured data to be used in simulations. The performance of the ge...
