Abstract
In this paper, a new nonlinearly time-varying weighting (NTVW) technique is proposed to mitigate the nonstationarity of bistatic clutter. The nonlinear factors contained in the range-varying characteristics of angle-Doppler frequency are taken into accounted by the method, and can effectively suppressing the bistatic clutter returns reflected from the far, middle and near distance scenarios. Moreover, the NTVW is a data-dependent method and can adaptively compensate the range nonstationarity of bistatic clutter without the prior knowledge of the moving platforms and the environment. The simulation results manifest that the NTVW has superior clutter rejection performance compared with the linear time-varying weighting and the traditional bistatic the space-time adaptive process (STAP) without any compensation strategies in the scenarios of different bistatic range.
