“…Moreover, the army is now equipped with multiple sorts of stealth missiles that have been put into actual operation, including but not limited to: the air-to-air stealth missile of the AIM-9X Sidewinder series, and the stealth cruise missiles of the AGM-129 and the AGM-129A series developed by the U.S; the stealth cruise missile of the Kh-102 series developed by Russia; and the stealth cruise missile of the Storm Shadow series developed by France. Through the unique design of stealth structure and the efficient use of stealth materials, the possibility is significantly lowered for these missiles to be intercepted by the enemy, thus greatly enhancing the penetration ability and survivability of these missiles in the battlefield [12][13][14][15][16][17][18][19][20][21].…”

In modern warfare, precision guided munitions have become one of the major equipment to attack and hit the enemy’s crucial value targets. In addition, they are the critical targets of the missile defense and anti-aircraft interceptor system of varying countries during interception and destruction, and the world has increased investment in missile defense. Therefore, the penetration and countermeasures capacities of missiles holds the key to the victory, and the stealth technology of tactical missiles provides a vital orientation for the future advancement of weapons and equipment technology. Based on the current military requirements, this paper summarizes the application of stealth technology in varying tactical missiles and analyzes the development trend of such technology in the future, which is expected to have great implications for further research and application of both stealth and anti-stealth technology.

“…Regarding the modeling of inhomogeneous targets with irregular shapes, target models are often simplified. For example, in calculating the aircraft wake scattering characteristics, the radial density gradient (RDG) model is adopted to approximate the wake vortex as a dielectric cylinder [4,5], and the adiabatic transport (AT) model regards the vortex wake as a circle whose cross-sectional radius is the function of the vortex distance [4]. All these methods reduce the complexities of calculation, but these approximations also reduce the abilities to accurately describe real scenarios.…”

This paper presents a method to finely model the arbitrarily irregular-shaped and inhomogeneous dielectric target. The target is first geometrically divided into a set of homogeneous and isotropic tetrahedral regions. Each region is precisely matched with a set of electromagnetic parameters. As a result, this can accurately model the target which has an extremely complex dielectric constant distribution and an irregular shape. Regarding the electromagnetic scattering evaluation of the established model, the method of moments (MoM) is adopted in consideration of the coupling between these tetrahedral regions, and the total scattering is obtained by solving the matrix equation. The above two computational sections are integrated into a self-designed software. One can just input the spatial distribution of the dielectric constant and then the designed software automatically processes the target’s geometric information and meshes the target. Finally, the scattered electric field and radar cross section (RCS) of the target are output from the software. The designed software provides an effective and accurate way to study the electromagnetic scattering characteristics of the complex inhomogeneous objects.
