Abstract: In modern warfare, various jamming techniques are employed to disrupt enemy radar systems using radio waves. The pull-off deceptive jamming technique misguides the enemy into incorrectly detecting the positions of allies, causing it to waste radar resources while protecting friendly information. The development and advancement of digital radio frequency memory (DRFM) have enabled the precise replication of received radar signals, making it difficult to distinguish between the deceptive range and velocity signals generated through this technique and signals reflected from actual targets. To address this, a countermeasure technique was developed that exploits the fact that a delay occurs when analyzing and replicating signals by focusing on detecting only the leading edge of the received signal to eliminate deceptive signals. This study simulates air-to-air radar operating environments and analyzes the performance of a leading-edge tracker-jamming countermeasure technique based on various indicators.
