“…As illustrated in Fig. 2 (where Tx refers to the transmission and Rx refers to the reception), two configurations are possible: the bi-static setup with two antennas [12], one antenna for transmission and one antenna for reception; the mono-static setup with only one antenna for transmission and reception [7]. The power transfer is characterised by the transmission coefficient in bi-static setup and the reflection coefficient in mono-static setup.…”

The passive millimetre‐wave identification (MMID) technology was introduced few years ago, exploiting the advantages of the passive ultra‐high frequency (UHF) radio frequency identification (RFID). The communication is based on backscattering modulation, related to the radar cross‐section (RCS) of the transponder. Thus, the need of accurate RCS measurement in the V‐band arises. This work presents two methods to measure the RCS of any antenna in the particular case of MMID from 57 to 66 GHz. The studied methods require some precautions in millimetre‐wave compared with measurements done in the UHF band. The two approaches highlight the methodology for accurate RCS measurement while the methods are evaluated through an example. A horn antenna is used as a MMID tag antenna and the RCS of the antenna is studied across three different loads as in UHF RFID: the short circuit, the open circuit and the matched load. The proposed methods provide a good accuracy and are validated by comparing the measurement results to the simulation.

“…Aside from the interesting mechanical properties of composite materials associated with environmental durability, the interaction of this class of materials with electromagnetic waves, particularly radar waves, has received special attention with fundamental importance in the area of stealth technology [1,7]. The effectiveness with which a radar system can detect a target depends primarily on how much of the electromagnetic energy illuminating the target is reflected back to the radar.…”

“…The effectiveness with which a radar system can detect a target depends primarily on how much of the electromagnetic energy illuminating the target is reflected back to the radar. According to literature [1,7], glass-fiber-reinforced composites are transparent to electromagnetic radiation in the microwave range, whereas carbon fiber laminates behave as reflective materials.

“…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.…”

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

Abstract. This paper has attempted to evaluate the radar cross section (RCS) of two furniture items in an indoor environment in a frequency range of 3–7 GHz of the ultra-wideband (UWB) range. The RCS evaluation is achieved through an extended version of the radar equation that incorporates the channel transfer function of scattering. The time-gating method was applied to remove the multipath effect, a phenomenon which typically occurs in the indoor environment. Two double-ridged waveguide horn antennas for both vertical and horizontal polarizations were used to obtain the transfer function of scattering of the furniture prior to analysis in order to derive their bistatic RCS. The RCS results validate the applicability of the proposed extended radar equation to the indoor propagation prediction.
