ISAR Imaging Method for Non-Cooperative Slow Rotation Targets in Space
Considering the electromagnetic scattering and ISAR echo of space non-cooperative targets with slow rotation characteristics,in this paper,combined with the motion characteristics of target rigid body,a spatial non-cooperative security ISAR imaging method based on SRMF and CLEAN algorithm is proposed.According to the motion feature of the target and the related parameters,firstly the model of the target geometry and the scattering echo is established,and then the echo signal is translational compensation and the slow angular velocity is estimated.Finally,a two-dimensional ISAR image of the target is achieved by estimating the angular velocity.Simulation results verify the effectiveness and practicability of the method.
