Abstract：Aimed at the problem that the reconnaissance receiver easily detects the information in direction of the conventional phased array radar and j ams,an angle deception method based on FDA (Frequency Di-verse Array)is proposed.This paper applies a small linear frequency shift is applied from channel?to?chan-nel,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 de-ception aimed at reconnaissance receiver.In addition,based on the analysis of deception principle,the pa-per 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.
