Phase Inconsistency Error Compensation for Multichannel Spaceborne SAR Based on the Rotation-Invariant Property
نویسندگان
چکیده
The azimuth multichannel technique has been widely used in synthetic aperture radar (SAR) systems for improving the resolution and expanding illumination area. However, due to phase inconsistency (PI) of different channels, image quality deteriorates significantly, including loss appearance ghost targets. In this letter, by exploiting rotation-invariant property steering vector SAR signal, a PI error compensation method is proposed based on estimation signal parameters rotation invariance (ESPRIT). Experimental results are presented using both simulated real data demonstrate performance method.

Abstract: This paper develops a continuous tangent motion model by approximating the relative trajectories between spaceborne Synthetic Aperture Radar (SAR) and its targets during every transmitting period and every receiving period as tangential segments. Compared with existing motion models, including the stop-go model and the continuous rectilinear model, the continuous tangent model is much...

متن کاملOptimal Baseline Design and Error Compensation for Bistatic Spaceborne InSAR
s: Bistatic SAR systems as opposed to monostatic SAR offer some degrees of freedom in choosing transmitter and receiver separately. In this paper, the spatial baseline in bistatic spaceborne InSAR and the requirements of optimal baseline are analyzed in many aspects. An equation to determine the optimal spatial baseline is derived, and one method to estimate and correct the baseline error cause...
متن کاملA Novel Array Error Estimation Method for Azimuth Multichannel SAR
Minimum side-zone power to center-zone power ratio (MSCR) method is presented to estimate array errors of azimuth multichannel synthetic aperture radar (SAR). Spaceborne azimuth multichannel SAR is one of the most promising candidates for achieving high-resolution wide-swath imaging. However, array errors brought in by instrument influences and aperture position errors need to be compensated. M...
