Abstract

Use of the range instantaneous Doppler (RID) approach is proposed, for reconstructing very high resolution inverse synthetic aperture radar (ISAR) of maneuvering targets. It is shown that, for spatial resolutions, the RID approach is superior to the conventional range Doppler (RD) method.

Abstract

The effects of specular multipath on the reconstruction of high resolution target image provided by an inverse synthetic aperture radar (ISAR) are investigated. First, a model of the received signal that takes into account the reflections produced by the surface of the Earth is defined. Then, the impulse response of the imaging system used to reconstruct the reflectivity function of the target is evaluated. Finally, the theoretical analysis is validated by some simulation results relative to different motion conditions.

Abstract

The problem of inverse synthetic aperture radar (ISAR) image reconstruction of targets at low elevation angle is considered. In this geometric conditions the main causes affecting the reconstructed ISAR image are: the multipath effect due to the reflection of the Earth surface and the angular motions of the target produced by external action like wind, fast maneuvering, and sea waves as in the case of ships. The aim of this work is to analyze the effects that the multipath and the target angular motions jointly produce on the ISAR image. The results show that multipath generates some artefacts in the image whereas the target oscillations undergo a spatial-dependent blurring of the point spread function of the ISAR system These theoretical results are validated by presenting some numerical examples relevant to aircrafts and ships in rectilinear or circular motion. A wide discussion on possible solutions of this problem is made in the conclusion.
