Improved SAR Motion Compensation without Interpolation
نویسندگان
چکیده
Motion compensation is an important part of SAR processing for high resolution airborne sensors, such as those flown on UAS’s. The non-ideal motion of the platform results in degraded image quality, but for known motion, corrections can be made. Traditional motion compensation requires a computationally costly interpolation step to correct translational motion greater than a single range bin. This paper presents an efficient new motion compensation algorithm that corrects this range shift without interpolation. The new method is verified with simulated SAR data and data collected with the NuSAR.

An Extended Wavenumber-Domain Algorithm Combined with Two-Step Motion Compensation for Bistatic Forward-Looking SAR
With appropriate geometry configurations, bistatic Synthetic Aperture Radar (SAR) can break through the limitations of monostatic SAR on forward-looking imaging. Thanks to such a capability, bistatic forward-looking SAR (BFSAR) has extensive potential applications. For the focusing problem of BFSAR, wavenumber-domain algorithm is accepted as the ideal solution. However, in practical application...
متن کاملRefined Motion Compensation for Highly Squinted Spotlight Syn- thetic Aperture Radar
This paper presents a motion compensation algorithm which is capable of dealing with large motion errors for highly squinted spotlight SAR. The approach consists of a phase error compensation, a shift to correct the delay time error and an interpolation/resampling in azimuth. For pulsed SAR with a 30° squint angle, the proposed algorithm compensates motion errors that are 10 times greater than ...
متن کاملImproved Motion Compensation for Wide- Beam Wide-swath Airborne Sar
In order to gain consistent focusing quality all over the imaging region for wide-beam wide-swath airborne synthetic aperture radar (SAR), higher motion compensation (MoCo) accuracy at the edge of the swath is needed. In this letter, an improved MoCo approach is proposed, and its performance is validated by using simulated data, as well as real data collected by a P-band SAR system.
متن کاملMotion Compensation for Squint Mode Spot- Light Sar Imaging Using Efficient 2d Inter- Polation
In the squint mode airborne spotlight synthetic aperture radar system using the range migration algorithm (RMA), autofocus (AF) technique yields poor results due to the squint spreading of the point spread function (PSF) of a scatterer. Thus, two-dimensional (2D) interpolation is required to direct PSF blurring in cross-range direction, to improve the cross-range resolution ∆y and to remove the...
متن کاملImproved Airborne SAR Data Processing by Blockwise Focusing, Mosaicking and Geocoding
Standard focusing of SAR data assumes a straight recording track of the sensor platform. Small non-linearities of airborne platform are corrected for during a motion compensation step while keeping the assumption of a stripmap geometry. In the case of high resolution and high frequency SAR systems, the navigation data may not be accurate enough to perform such a motion compensation; SAR systems...
