Moving Target Indication with a Millimeter Wave Monopulse SAR
نویسندگان
چکیده
Synthetic aperture radar offers high resolution images of a static scene while moving objects are often smeared and displaced in azimuth. Ground moving target indication with a monopulse system makes it possible to correct the azimuth displacement and measure an accurate individual radial velocity component of moving targets via special processing techniques. The presented method requires the focused data from the sum and difference monopulse channels and is based upon specific deviations in the Doppler monopulse ratios due to object movement. For an experiment with the airborne millimeter wave radar system MEMHPIS and amplitude-comparison monopulse processing, frequency spectra and resulting accurate target velocities and positions are presented. They are used to verify the developed algorithms.

Maurice Rüegg Ground Moving Target Indication with Millimeter Wave Synthetic Aperture Radar
Ground moving target indication (GMTI) for synthetic aperture radar (SAR) provides information on non-static objects in radar imagery of a static ground scene. While general applications cover a wide area of topics from ocean current measurements to glacier ice flow, millimeter wave (mmW) SAR is well suited for traffic monitoring, reconnaissance, and identification of special target movements i...
متن کاملHigh Resolution Millimeter Wave SAR for Moving Target Indication
Synthetic aperture radar (SAR) is an imaging radar technique that provides mapping of static ground scenes. Some existing and forthcoming SAR systems thereby provide very high resolution in the centimeter domain. While high azimuth resolution is achieved by signal processing techniques, range resolution for a traditional frequency modulated system is solely dependent on the signal bandwidth. Fo...
متن کاملMoving target detection in foliage using along track monopulse synthetic aperture radar imaging
This paper presents a method for detecting moving targets embedded in foliage from the monostatic and bistatic synthetic aperture radar (SAR) data obtained via two airborne radars. The two radars, which are mounted on the same aircraft, have different coordinates in the along track (cross-range) domain. However, unlike the interferometric SAR systems used for topographic mapping, the two radars...

متن کاملPosition correction of moving targets in SAR-imagery
Standard SAR-processing methods are based upon the assumption of a static scene. If targets are moving, their positions in the SAR-image are translated in azimuth and defocusing may occur. In this paper, some methods for the detection and imaging of moving targets and the estimation of their real positions are discussed, such as monopulse and DPCA. Experimental results are shown on correction o...
