| Abstract: | At present,the movement instability of the radar platform and the distance error coefficient departs from a natural number,are the two main reasons which conduce the quality of clutter-suppression.A new GMTI real-time Algorithm used for Airborne Dual-Channel SAR will be presented in this paper,which has the advantages of both the Self-adaptive Interpolation and Doppler range DPCA.After analyzing the principle of this new algorithm,we would take a simulative aircraft as an example,in which a distance error c... |
