Countering self‐protection smeared spectrum jamming against chirp radars

Chirp radars are vulnerable to various types of deceptive jamming for example, smeared spectrum (SMSP) that generates multiple false targets, which lead and lag the true target. Unfortunately, radar system cannot distinguish target from ones because signal looks like echo. A new anti-jamming technique suppress targets identify easily is introduced. The proposed benefits fact SMSP has a different frequency modulation slope signal. Therefore, differences between echo can be identified. efficiency confirmed by theoretical analysis simulation experiments.
