Abstract_FL In the ground attack mission,the attack plan needs to be formulated and distributed to the at-tack aircraft based on the threat source intelligence data obtained in advance with the help of the tactical mission planning system.The passive radar reconnaissance and direction finding system can calculate the location infor-mation of threat sources and provide it to the task planning system by processing the received signal.When the enemy radar is a frequency diverse array system rather than a phased array system,the bending characteristics of the beam of the frequency diverse array radar can deceive the passive direction finding system.On the basis of analyzing the basic structure of frequency diverse array radar,this article compares the phase plane characteris-tics of phased array and frequency diverse array,and takes the interferometer direction finding system as an ex-ample to study the deception effect of frequency diverse array radar compared to phase method direction finding.The deception simulation results of several nonlinear FDA arrays show that the virtual transmitter intersection co-ordinate deviation of log-FDA is greater than that of sin-FDA.When the x-axis coordinate of the interferom-eter is xG =300 km,the virtual transmitter intersection coordinates gradually approach the actual position of the FDA array as the y-axis coordinate of the interferometer increases.The intersection offset is log-FDA>sin-FDA>reciprocal-FDA.
