Demonstration of advanced reconnaissance techniques with the airborne SAR/GMTI sensor PAMIR
PAMIR (Phased Array Multifunctional Imaging Radar) is an experimental airborne radar system that has been designed and built by the Research Institute for High Frequency Physics and Radar Techniques (FHR) of Forschungsgesellschaft für Angewandte Naturwissenschaften (FGAN). The goal is to meet the growing demands for future reconnaissance systems with respect to flexibility and multi-mode operat...
متن کاملRoad-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 کاملSpace-Time Adaptive Processing: Algorithms
In this lecture, we present some suboptimum STAP algorithms for radar, applied to moving target indication. In addition, we show some MTI results obtained with the multi-channel airborne experimental radar AER-II of FGAN-FHR.
متن کاملSar and Mti Processing of Sparse Satellite Clusters
The concept of radar satellite constellations has been proposed in the literature and is currently under research. These constellations possess the wide angular coverage necessary for performing spaceborne MTI and the spatial sampling necessary for wide-area SAR. However, the constellations form arrays that are sparsely populated, three-dimensional, and irregularly spaced. Therefore, current SA...
متن کاملSAR and Moving Target Indication
Synthetic aperture radar provides high-resolution images of the non-moving ground scene, but fails to indicate and position moving objects. A short review of the motioninduced effects occurring in SAR images will open this lecture. Like in special airborne MTI systems, the solution to the SAR MTI problem is to use an array of antennas or subapertures and several receiving channels to cancel the...
