Study Of Polarization And Variable Polarization Technology Of Microstrip Antennas

The simulation of polarization information processing and dual-polarized microstrip array antenna are the main content, which is based on radar probing system background and focus on microstrip antennas research. The job is divided into two parts.Firstly, introduction polarization technology basic theory, including polarized concept, ellipse of polarization attribute theorem, partial polarized waves attribute and decomposition. Take the goal, the disturbance and the clutter polarized characteristic as the foundation, the introduction goal scattering matrix and the scattering cross-section concept, carries on the simulation analysis using MATLAB software to two kind of models spotting polarization diffusion properties. In view of the partial polarized situation SINR polarizing filter, using Lagrange multiplier method and the union parameter matrix nature, deduces the complete solution of the optimization and finally produces the numerical analysis examples.Secondly, take the microstrip array and the feed technology as the foundation, analyses deeply dual-polarized microstrip antennas array polarized characteristic. Using HFSS software to carry on the simulation design to the L wave band plane microstrip array antenna, finally has produced the simulation result.
