Abstract

Abstract

High velocity and Ionosphereic both modulate the phase of low carrier frequency wide-band linearly frequency modulated radar signal , It make the resolution of Inverse SAR (ISAR) image lower. In order to get clean ISAR image, the effect of high velocity and ionosphereic are both must be removed. Firstly, signal model of ionosphereic target with high-velocity are deduced. The high order phase signal parameter estimation method is proposed, using discrete polynomial-phase transform. Motion compensation is done with the estimated values got by this method. Simulation experiments show that the parameters can be estimated right, it can improve the ISAR image deformed by hyper-velocity and ionosphereic.
- Inverse SAR (ISAR),
- Ionosphereic,
