An UWB Super-Resolution Method of Motive Target

The high frequency UWB radar echo of a static target can be modeled as ARMA and approached by state-space technique. But this method is only valid when the target is static. Further, the motive target model of UWB radar is presented. This model is composed of a static model and a polynomial phase caused by the motion of target, and based this character a cyclostationary method can be used to estimate the motion parameters of the target. After the motive target model compensated by the estimated parameters, the eigenvalues can be extracted by the first method. The result of simulations shows the proposed method can correctly obtain the super-resolution of the motive target
