The Imaging Research of the Ground Moving Targets in Forward Scattering Radar
The present shadow inverse synthetic aperture radar (SISAR) imaging algorithm is derived based on some assumptions for air moving objects such as long baseline, large target size and so on. For the forward scattering radar (FSR) system to detect ground moving targets, the assumption conditions are often unsatisfied because of relatively small objects size, the strong ground clutter and the short baseline length. Furthermore, the assumptions will result in distorted imaging results for the extraction of profile median line and height difference using the present imaging algorithm. To obtain the accurate imaging results of ground moving target, the more accurate signal model for ground moving target is first time presented based on Fresnel-Kirchhoff diffraction formula and high order phase approximation methods, and the modified imaging algorithm is also proposed for the accurate profile reconstruction of ground moving target. Finally, the effectiveness is verified by simulation results.
