Parameter Estimation for Interrupted Sampling Repeater Jamming Based on ADMM
Sensors, 2021 By repeatedly sampling, storing, and retransmitting parts of the radar signal, interrupted sampling repeater jamming (ISRJ) based on digital radio frequency memory (DRFM) can produce a train of secondary false targets symmetrical to the main false target,
