Abstract

The impact of moving target on the one-dimensional coherent imaging in stepped radar is analyzed in this paper. A cross-correlation-based estimation method of radial velocity is proposed. It is proven by analytical derivation that the cross-correlation analysis on adjacent pulses yields the quantity related to the radial acceleration and velocity of moving target, based on which the radial motion parameters of targets can be precisely estimated. The simulation results demonstrate that this approach can estimate the radial acceleration and velocity with high precision at high signal-to-noise ratio, and compensate for the raw data effectively. As a result, good high-resolution one-dimensional image could be gotten.
