Design of SLB systems in the presence of correlated ground clutter

Impulsive interference might increase the number of false alarms in a surve illance radar. The sidelobe-blanking (SLB) device, used in connection with the radar system, reduces the number of false alarms when the interference impinges on the antenna sidelobes. The paper describes how to design an SLB system operating in correlated Gaussian clutter with known Doppler spectru m plus white Gaussian thermal noise and impulsive interference. Closed-form expressions of the probability of false alarm, the probability of blanking a target received in the main lobe, and the probability of blanking a cohe rent repeater interference (CRT) are also derived for two statistical model s of target/CRI, namely: Swerling-0 (known amplitude and random phase), and Swerling-I (random amplitude and random phase).
