Abstract
Deceptive jamming is a popular electronic countermeasure (ECM) technique that generates false targets to confuse opponent surveillance radars. This work presents a novel approach for hiding the actual target while producing multiple false targets at the same time against frequency diverse array (FDA) radar. For this purpose, the modified FDA radar is assumed to be mounted on the actual aircraft. It intercepts the opponent’s radar signals and transmits back to place nulls in the radiation pattern at the desired range and direction to exploit FDA radar’s range‐dependent pattern nulling capability. The proposed deceptive jammer produces delayed versions of the intercepted signals to create false targets with multiple ranges to confuse the opponent’s radar system. The novel mathematical model is proposed whose effectiveness is verified through several simulation results for different numbers of ranges, directions, and antenna elements.

(ii) The algorithm works against the opponent frequency diverse array (FDA) radar and hides the actual target from it (iii) For this purpose, enemy radar pulse is captured by the target FDA radar, and null is placed at the radar range to hide its own target alongside after its time modulation (iv) It is effective to tackle ground-based opponent FDA radar in its own territory (v) The proposed technique efficiently works without help of ground-based wave-scattering reflectors or advance escort-free-drone jammers (vi) The proposed algorithm confuses the opponent FDA radar by multiple false targets at different userdefined ranges
A novel approach in the field of deception jamming has been developed in this research which hides actual target and displays multiple fake targets at different arbitrary ranges along the same direction to the enemy radar
