Following the recent advancements in radar technologies, research on automatic target recognition using Inverse Synthetic Aperture Radar (ISAR) has correspondingly seen more attention and activity. ISAR automatic target recognition researchers aim to fully automate recognition and classification of military vehicles, but because radar images often do not present a clear image of what they detec...

This paper describes the development and testing of a digital radio frequency memory (DRFM) kernel, as well as some of the functionality which has been added to the system to make it a fully-fledged hardware in the loop (HIL) radar environment simulator (RES) system for radar testing and evaluation.

We describe in detail the theoretical and practical implementation aspects of a simulation for marine radars which can, in particular, be used in multistatic configurations. Since the simulator is intended to deliver pseudo-raw signals, it can be used later as a tool to benchmark and improve post-processing algorithms such as bistatic synthetic aperture radar focusing algorithms and ship wake d...

In this paper a SAR simulator able to provide images presenting appropriate speckle statistics is introduced. The simulator is able to generate both Exponential (fully developed speckle) and K-distributed speckle statistics, according to surface and radar parameters. It is based on sound physical models for the evaluation of the number of equivalent scatterers per resolution cell. The proposed ...

At short wavelengths, the attenuation of the radar signal due to precipitation along its path constitutes a major source of error for radar rainfall estimation. The different techniques developed to correct for this attenuation generally assume that the radar sampling volumes are homogeneously filled by rainfall. However, rainfall is highly variable over a large range of scales, and the influen...

In order to generate a continuous radar simulation image to meet the practical need of navigation simulator, a method is presented to generate radar simulation data extracted from multi-scale S-57 standard electronic charts. In this paper, outliers index algorithm based on forward distance is presented firstly to clip the boundary line. Then buffers are built to merge and de-duplicate data acco...

i Abstract A radar simulator for polarimetric radar variables including reflectivities at horizontal and vertical polarizations, the differential reflectivity and the specific differential phase, has been developed. This simulator serves as a testbed for developing and testing forward observation operators of polarimetric radar variables that are needed when directly assimilating these variable...
