Abstract
Since the phase⁃coded echo signal of high⁃velocity moving target can’t be long⁃term coherent integration,a meth⁃od of double⁃frequency conjugate processing is proposed in this paper,in which the double⁃frequency conjugate processing and Keystone transform are adopted to solve the range migration and velocity ambiguity of high⁃velocity moving target simultaneously and realize effective coherent integration. The two targets echo simulation signals were used in experiment. The experimental re⁃sults indicate that the method is effective.关键词
