Research on Time-Domain Deceptive Jamming Method for Passive Radar

The passive radar's excellent concealment and cost advantages make it attractive in various scenarios and specifically effective against drone swarms. This paper investigates time-domain deceptive jamming methods to counter passive radar systems. To achieve TDOA jamming effects, we propose using signal synthesis from drone swarms to mislead the positioning results of passive radar. Through the establishment of theoretical models and simulation experiments, it is demonstrated that the proposed method can effectively achieve TDOA jamming of passive radar by altering signal phase, pulse duty cycle, and retransmission delay. The proposed method can effectively disrupt the precise positioning of passive radar, thereby deceiving enemy systems. This technique can be employed in radar countermeasures and electronic warfare.
