Improvement of Navigation Accuracy using Tightly Coupled Kalman Filter
In this paper, a mechanism is designed for integration of inertial navigation system information (INS) and global positioning system information (GPS). In this type of system a series of mathematical and filtering algorithms with Tightly Coupled techniques with several objectives such as application of integrated navigation algorithms, precise calculation of flying object position, speed and at...
متن کاملMutual Coupling Analysis Using Fdtd for Di- Electric Resonator Antenna Reflectarray Radiation Prediction
A simulation technique based on Finite-Difference TimeDomain (FDTD) is used to analyze mutual coupling effects in reflectarray environment. The neighbouring element method has the ability to analyze actual non-identical reflectarray unit-cell accurately compared to the traditional Floquet simulation which assumes all unitcell is identical. It is also found that the nearest neighbouring unit-cel...
متن کاملA Varactor Loaded Reflectarray Antenna
A new approach for beam steering in reflectarray applications is introduced in this paper. The progressive phase distribution is achieved by loading each microstrip patch element with a varactor diode on the radiating edges. The scattering characteristics of a single varactor loaded patch will be first presented. Then, as a test of the beam steering capability, a five elements linear reflectarr...
متن کاملCoupled dipole method with an exact long-wavelength limit and improved accuracy at finite frequencies.
We present a new formulation of the coupled dipole method that accounts for local-field effects and is exact in the long-wavelength limit. This formulation also leads to improved accuracy of the description of light-scattering processes at finite frequencies.
متن کاملRing Shaped Compact Microstrip Reflectarray Antenna
Regularly shaped compact microstrip antennas have a small size but their gain is insufficient for most applications. Therefore, a ring-shaped compact microstrip reflectarray with microstrip antenna feed has been proposed. Different configurations, namely, 1 × 3, 3 × 1, plus-shaped and 3 × 3 have been analyzed. The 3 × 3 configuration yields an optimum gain of 10. 8 dBi and a narrow beamwidth of...
