“…This requirement has been already investigated in many other radar studies. As a matter of fact, different structures able to backscatter the radar signal in many directions both in azimuth and in elevation have been produced and/or only simulated [14][15][16] . In the present study, three types of artificial reflectors (AR) with an effective target detectability in many directions have been investigated (Figure 4 RCS performances of the selected passive radar reflectors have been simulated considering different azimuth (φ) angles of incidence radar waves.…”

The lack of stable and coherent natural targets can threat the effectiveness of Interferometric Synthetic Aperture Radar (InSAR) applications. To overcome this issue, active and passive radar reflectors are designed. Thanks to their low cost of construction and maintenance, passive radar reflectors are even more employed as coherent targets to assess potential displacement measurements of land, buildings, and infrastructures. In the present study, different types of passive radar reflectors are investigated by simulating their backscattering characteristics through a 3D electromagnetic software and by calculating their radar cross sections at different azimuth and incidence angles. Simulation results have been examined by considering the characteristics of current SAR satellite missions orbiting on different planes (Sun-Synchronous Orbit/Mid-Inclination Orbit) and considering both passes (Ascending/Descending), as well as by analyzing different orientations of SAR antenna (i.e., Right/Left look sides and incidence angles). Advantages and disadvantages of the investigated passive radar reflectors are highlighted in terms of their visibility on multiple Line Of Sights (LOS). Two carrier frequencies have been selected, that are close to those of operational SAR satellites: 5.405 GHz (C-band) and 9.66 GHz (X-band).

“…The aim of studying reliability is to preempt or reduce potential malfunctions in the product's design. A comprehensive comprehension of equipment reliability, throughout all stages of the equipment's lifecycle, facilitates the inclusive implementation of support requirements, making these provisions more rational and practical [10]. This, in turn, helps in expediting the intended function of the equipment and curtails the overall cost of lifecycle support.…”

This study examines the impact of varying wind and wave levels on the radar cross section (RCS) analysis of ship targets at different sea surfaces. A ship model was established and the far-field single station RCS of ship targets was analyzed under various sea conditions using a hybrid algorithm of physical optics and moment method (PO-MOM). The study utilized FEKO software to simulate and calculate the far-field single station RCS of the European Buffalo class hovercraft, while also improving the hovercraft model to account for seawater. Additionally, the study analyzed and studied the target RCS of the ship under different sea conditions using the PO-MOM hybrid algorithm, and ultimately utilized the CSI algorithm to compensate for it. The findings indicate that as the sea level rises, the ship's RCS decreases.

In this paper, we present the design and analysis of omnidirectional retroreflective surfaces made of trihedral, corner reflectors to enhance the monostatic radar cross section of otherwise low back-scattering surfaces. The proposed designs can be mounted on helmets and used for various applications such as improving the collision avoidance of automotive radar systems in the presence of bicyclists and motorcyclists or improving collision prediction radars in contact sports or other risky environments, where helmets are used. To address these applications, we analyze the coherent response of the proposed designs.
