Description

technical field [0001] The invention belongs to the field of communication technology, and further relates to a method for estimating target polarization parameters based on full-polarization conformal MIMO (Multiple Input Multiple Output) radar in the field of radar technology. The polarization parameter of the moving target estimated by the invention can be used for the identification, tracking and detection of the moving target by the full polarization conformal MIMO radar. Background technique [0002] The conformal array antenna refers to the array antenna attached to the surface of the carrier and bonded to the carrier, that is, the array antenna needs to be conformally installed on a fixed-shaped surface to form a non-planar conformal antenna array. In modern wireless communication systems, conformal array antennas are known as antennas because they can conform to the surface of high-speed carrier platforms such as aircraft, missiles, and satellites without destroying...
