On FDA RF localization deception under sum difference beam reconnaissance

Different from the conventional phased-array, frequency diverse array (FDA) introduces a small frequency increment across the array element, thus yielding a range-and-time-dependent beampattern. This property motivates the application of FDA in radio frequency (RF) localization deception. In this paper, the sum and difference beams algorithm is used to test the effectiveness of the proposed method in FDA reconnaissance. Both theoretical analysis and simulation results show that the sum and difference algorithm cannot achieve FDA radar reconnaissance effectively and accurately. Therefore, compared to phased-array, FDA has a better RF localization deception performance.
