| Abstract: | The moving model of target limited by RMTI method is extended to the movement with constant accelerate in this paper. A method based on linear-variantcoefficient-difference-equation for moving target indication is presented. And then we analyse the relationship between its snr gain and the temporal correlation coefficient,spacial correlation vector of the background clutter. Experimental results have shown it can improve the detectability of moving target with constant acceleration under the low snr condition effectively. |
