title = "On transmitter polarization optimization for target scattering matrix estimation",
abstract = "The knowledge about target scattering matrix is essential for adapted and matched polarimetric target illumination. The Cramer-Rao bound (CRB) for target scattering matrix estimation in the presence of compound Gaussian clutter is known to be the function of transmitter polarization. The optimized probing waveform polarimetry design procedure thus can be performed to minimize the CRB for the 'best' target scattering matrix estimation. However, to find the optimal transmitter polarization for target scattering matrix estimation, a suboptimal lattice search has to be used in the current method. In this contribution, we demonstrate that the mentioned CRB minimization for target scattering matrix estimation against compound Gaussian clutter can be achieved by simply transmitting several couples of probing pulses with orthogonal polarizations, for example, by transmitting alternately a number of horizontally and vertically polarized pulses just like the traditional scheme for directly measuring the target scattering matrix in the absence of clutter.",
