Abstract:Aimed at the problem that the reconnaissance receiver easily detects the information in direction of the conventional phased array radar and jams, an angle deception method based on FDA (Frequency Diverse Array) is proposed. This paper applies a small linear frequency shift is applied from channeltochannel, resulting in FDA pattern function related with range between channels to make electromagnetic wave power bend in different ranges, thus forming a virtual radiation source, and achieving the goal of angle deception aimed at reconnaissance receiver. In addition, based on the analysis of deception principle, the paper discusses the deception effects of frequency offset and space between channels. The results of Matlab simulation show that by this method the angle deception can reach up to 90 degrees at specific ranges when some factors are properly fixed.
