| Popis: | The purpose of this paper is to find a more effective way to reconstruct the structure of a target. In this paper, the principle of ISAR and InISAR signal formation and imaging are analyzed by the perspective of analyzing the target linear frequency modulation echo signal and combining with ISAR imaging algorithm. We proposed a method of InISAR scattering point extraction technology based on CLEAN algorithm and threshold processing. And compare it to the method of image matching reconstruction. The simulation results show that the InISAR reconstruction technique based on scattering point extraction method is a more effective one, with higher detection probability and has an ability to suppress the influence of noise and sidelobe effect, under the condition of noise. |
