A study on RCS of missile models using the method of moments

Simulation of electromagnetic signals scattered by objects is a complex issue, although its fundamentals have long been known. In the design of modern military aircrafts and vessels in general, advantages can be taken from their physical properties for reducing the intensity of radar signals, which are scattered back to the enemies. This leads to the definition of stealth plane or ship. A couple of design guidelines should be followed in order to achieve this goal. One of them is the geometric optimization of the vehicle shape. Much of the literature on this subject is classified; moreover, the computing burden to tackle such a design is quite demanding. In this work, a conventional PC running a commercial electromagnetic code based on a modified Method of Moments is used to analyze four different simplified missile models. Design rules are established in view of reducing the monostatic radar cross section (RCS) scattered signal.
