Reconstruction of the Scattering Function of Overspread Radar Targets
نویسندگان
چکیده
This paper addresses the problem of stochastic radar target measurement. We develop an algorithm that allows for the reconstruction of the scattering function of a WSSUS radar target from the autocorrelation of the response of the target to a deterministic sounding signal. While conventional methods are applicable only when the scattering function is supported on a rectangle with area less than one, our method can handle area one support sets of arbitrary geometry. Based on the suggested theoretical recovery procedure, we propose a scattering function estimator.

Reconstruction and Estimation of Scattering Functions of Overspread Radar Targets
In many radar scenarios, the radar target or the medium is assumed to possess randomly varying parts. The properties of a target are described by a random process known as the spreading function. Its second order statistics under the WSSUS assumption are given by the scattering function. Recent developments in the operator identification theory suggest a channel sounding procedure that allows t...

متن کاملMicrowave Imaging Using SAR
Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
متن کاملEffect of Curved Path Monopulse Radar Platform’s Grazing Angle on Height of Floated Targets Detection
Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...
متن کاملروشی جدید برای تخمین همزمان تاخیر و داپلر از تابع ابهام: تلفیق فرآیندهای تصادفی و پردازش های مکانی برای حذف کلاتر و نویز
In this paper a new method is introduced for jointly delay and doppler estimation in ambiguity function based radars. In this method firstly each cell of ambiguity function is considered as a random variable, then an stochastic processes is estimated for each cell based on its value during consecutive radar scans. In the second step the ambiguity function is divided to high probability target a...
