Radar cross section

Technological evolution in signal processing area that has been made in last decades led to seriously improvements in radar performances. Increasing of radar range by improving of sensitivity has been made the builders of aircraft and other military systems to try to decrease the radar cross section of these kind of equipment. The radar cross section is a matter of survivability for an aircraft and, for this, any measure designed to decrease this important parameter has to be taken into consideration. This deals with defining radar cross section, presenting some method for reduction and is focused on analyzing some features of radar absorbing materials with variable conductivity.
