The “masking effect” of unresolved targets always results in missed detection and inaccurate parameter estimation. A feasible approach to separate the unresolved targets is improving the range resolution by increasing the signal bandwidth. In thi

In the conventional superresolution, multiple targets are usually separated based on the differences in their locations or Doppler frequencies. The polarization scattering matrix (PSM), as a unique “label” of a target, is very beneficial to radar
