In the recent years, an increasing interest towards enhanced and more frequent operations at high altitudes has been demonstrated both by aerospace industry and academics. In particular, many institutions and companies are developing the so-called HAPS (High Altitude Platform Stations, [1] - [3] ), high altitude balloons provided with low-thrust propulsion systems able to maintain their position over a target. These vehicles are provided with power generation systems and are able to perform long-term missions of weeks or even months.

To set conservation project in sustainable human development means to understand in-becoming reality, turning the static vision into a dynamic approach that considers life cycle as theoretical-methodological base, articulated in different and integrated steps. Historical architecture, in Mediterranean basin, assumes a type-morphological structure in coherence to microclimatic characters of site, defining the optimization of energetic relationships with surrounding natural environment.

The focus of this paper is the evaluation of the mono-static Radar Cross Section (RCS) of a commercial Drone (IRIS) through both simulation and measurements in the 1-4 GHz frequency range. In particular, for the simulations an approximate model of the drone geometry and its material complex permittivity was carried out by means of an electromagnetic CAD. Most importantly, measurements have been performed in an anechoic chamber equipped with a network analyzer and a horn antenna. The obtained results show RCS values between-18 dB and-1 dB in the 1-4 GHz frequency range.
