Road-Aided Ground Slowly Moving Target 2D Motion Estimation for Single-Channel Synthetic Aperture Radar
To detect and estimate ground slowly moving targets in airborne single-channel synthetic aperture radar (SAR), a road-aided ground moving target indication (GMTI) algorithm is proposed in this paper. First, the road area is extracted from a focused SAR image based on radar vision. Second, after stationary clutter suppression in the range-Doppler domain, a moving target is detected and located i...
متن کاملA Study for Cosmo-skymed Sar Multi-beam of Second Generation (msar-2g)
This paper discusses the potentialities obtained by splitting the antenna of the COSMO-SkyMed SAR developed by Alenia Spazio under contract of Italian Space Agency and Italian Ministry of Defence into multiple sub-apertures. The modified sensor is shown to allow: (a) clutter cancellation and detection of slowly moving ground targets for surveillance purpose, (b) sea current/wave monitoring by a...
متن کاملEffect of Curved Path Monopulse Radar Platform’s Grazing Angle on Height of Floated Targets Detection
Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...
متن کاملMultiresolution Signal Processing Techniques for Ground Moving Target Detection Using Airborne Radar
Synthetic aperture radar (SAR) exploits very high spatial resolution via temporal integration and ownship motion to reduce the background clutter power in a given resolution cell to allow detection of nonmoving targets. Ground moving target indicator (GMTI) radar, on the other hand, employs much lower-resolution processing but exploits relative differences in the space-time response between mov...
متن کاملDetection of Ground Moving Targets for Two-Channel Spaceborne SAR-ATI
Many present spaceborne synthetic aperture radar (SAR) systems are constrained to only two channels for ground moving target indication (GMTI). Along-track interferometry (ATI) technique is currently exploited to detect slowly moving targets and measure their radial velocity and azimuth real position. In this paper, based on the joint probability density function (PDF) of interferogram’s phase ...
