New Benchmark Radar Targets for Scattering Analysis and Electromagnetic Software Validation

Abstract

Abstract-A validation process, in which simulations and measurements are compared, is necessary to have confidence in the results obtained by numerical methods that solve scattering problems. This paper presents Radar Cross Section (RCS) measurements of new targets suitable for electromagnetic software comparison and validation. These measurements can be used as an RCS reference data for testing existing and future codes, as well as for the analysis of the scattering mechanisms.

RCS measurements and predictions of different targets for radar benchmark purpose

“…The truncated cone constitutes a further step in complexity with respect to the cylinder. More details about the geometry of these two targets can be found in [8]. The third target is a conosphere of a similar height that the former targets.…”

Comparative study of miscellaneous methods applied to a benchmark, inlet scattering problem

“…The cavity was measured in the anechoic chamber of the Detectability and Electronic Warfare Laboratory (DEWLab, INTA, Spain), where the typical layout of a standard straight RCS measurement range is deployed (see Fig. 4) [13]. The target under test – TUT – is located at one end of the chamber, over a foam column driven by an azimuthal positioner, and the transmitting–receiving antenna, supported by a tripod, is situated at the opposite end.…”

“…Responses coming either a bit after or a bit before the main response from the target are filtered out (because of the resonant behaviour of this target a wide enough gate was considered). With the combination of these two techniques, a maximum overall measurement error of ± 0.79 dB (for levels above − 45 dBsm) was estimated (see [13] for further information).…”

Measurement and evaluation of radar cross section for furniture in an indoor propagation channel

“…Depending on the target size and selected frequency range, RCS can be investigated in either an outdoor environment, indoor environment, or inside an anechoic chamber. Miacci et al (2012), Nicolaescu and Iubu (2007), and Bocanegra et al (2008) examined the RCS of scattering objects in an anechoic chamber. Esposti et al (2007) and Pongsilamanee and Bertoni (2004) analyzed the RCS of typical building walls, and Jong and Herben (2004) investigated the scattering of trees.…”
