摘要
This study reports on a novel technique for the estimation of the target total rotational velocity of a non-cooperative target. The technique makes use of the second-order local polynomial Fourier transform to estimate the hitherto unknown component of the velocity vector in the radar line-of-sight direction, and three-dimensional (3D) interferometric inverse synthetic aperture radar (ISAR) imaging the target. The aspect-independent 3D size and shape of a target - an important metric for automatic target recognition - can thus be estimated. Cross-range focus in the component 2D ISAR images is also improved in the process. Results obtained from extensive simulations demonstrate the feasibility of the proposed approach.
