Assemble An Active Cancellation Stealth System.

The article focuses on hiding a target from an inquisitive radar system under changing conditions through an active stealth cancellation system. Digital radio-frequency memory (DRFM), field-programmable-gate-array (FPGA) technology and a phased-array technique are used to design an active cancellation stealth system. With the phased-array technology, the required waveforms are generated to cancel reflected radar returns.
