  • This paper firstly studies the characteristic of the UWB radar frequency response and presents a parameterized method to extract the poles of UWB still target. This method regards the high frequency echo as an ARMA model and poles of this ARMA model express the scattering type and range of the scatter. Secondly, according the actual situation, the motive target model of UWB radar is presented. This model is composed of a still model and a polynomial phase part which is caused by the motion of target. 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 state space method. Simulation shows 1-D range and scattering mechanism can be correctly obtained and proves the validity of the method.
