Theory of polarization matched filter and band characteristics based on polarization transformation

Based on the polarization basis transformation, the optimum polarization receiver is obtained via eign-vector and eign-value of a matrix in partial polarization case. The polarization white filter (PWF) is presented, which is compared with the polarization matched filter (PMF), and the polarization white and matched filter (PWMF) is put forward. At last, the band circle is derived for the band of the polarization receiver based on the polarization basis transformation. All are useful for polarization information optimum processing for receiving and filtering.
