The radar target's reconstructed high-resolution images provide important features for target identification. Normally, the radar images are obtained with the cascaded steps of translational motion compensation (TMC), image reconstruction and rotation velocity (RV) retrieval for inverse synthetic aperture radar (ISAR). It is found in this paper that the high-resolution target's image can be obtained...
In this paper, the shadow inverse synthetic aperture imaging method for non-perpendicular crossing targets is studied. Errors of the current signal model in both amplitude and phase are analyzed in this case and a more appropriate selection of the image plane is given. Modified signal model and imaging method are presented and evaluated by simulation results, which show that the given model fits the...
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...
The purpose of this paper is to solve the imaging problems of one-stationary bistatic synthetic aperture radar (BiSAR) squint mode. Through the analysis of the target's two-dimensional spectrum, an improved chirp scaling algorithm (CSA) is got. It can deal with the space variability of this kind of BiSAR and the simulation is done to verify the validity and feasibility of this algorithm.
