MODELING AND SIMULATION OF ACTIVE CANCELLATION STEALTH SYSTEM: BASED ON RF

摘要

Active cancellation stealth technology can be used in airplane- and other-type equipment. In these systems the target must emit a cancellation wave to coincide with an incoming pulse, with the right amplitude and phase to cancel the reflected wave. The difficulty lies in achieving the cancellation accurately and in real time; including obtaining its wave's parameters as well as controlling it precisely [1]. We designed a model of an active cancellation stealth system based on digital radio frequency memory (DRFM), and a radar signal processing system for a coherent video simulation model using Matlab/Simulink.
