Seminal bistatic inverse synthetic aperture radar (ISAR) work that was presented by Martorella et al. about a decade ago has demonstrated that an equivalent monostatic configuration can be used to approximate the bistatic configuration under certain constraints. This allows us to greatly simplify the signal processing that leads to the formation of a bistatic ISAR image. Nevertheless, when such constraints are not fully satisfied some distortions may be introduced. In this paper, such distortions are studied in detail and a reduction of them is proposed that is based on the use of superresolution techniques.

Abstract
Seminal bistatic inverse synthetic aperture radar (ISAR) work that was presented by Martorella et al. about a decade ago has demonstrated that an equivalent monostatic configuration can be used to approximate the bistatic configuration under certain constraints. This allows us to greatly simplify the signal processing that leads to the formation of a bistatic ISAR image. Nevertheless, when such constraints are not fully satisfied some distortions may be introduced. In this paper, such distortions are studied in detail and a reduction of them is proposed that is based on the use of superresolution techniques.File in questo prodotto:
