A radar system with surveillance tasks equipped with an electronically scanned antenna is considered here, and a two-step scanning policy is developed and analyzed. The scanning period is divided into two phases, namely, an alert phase, where the antenna beam rotates to illuminate the monitored area, and a confirm phase, where a subset of ambiguous (i.e., with signal-to-disturbance ratio close to the threshold level) alarms from the alert phase is revisited. Numerical results show that the proposed alert-confirm detection can improve the system performance in terms of quickness of detection and rate of detections from the same target.

Abstract
A radar system with surveillance tasks equipped with an electronically scanned antenna is considered here, and a two-step scanning policy is developed and analyzed. The scanning period is divided into two phases, namely, an alert phase, where the antenna beam rotates to illuminate the monitored area, and a confirm phase, where a subset of ambiguous (i.e., with signal-to-disturbance ratio close to the threshold level) alarms from the alert phase is revisited. Numerical results show that the proposed alert-confirm detection can improve the system performance in terms of quickness of detection and rate of detections from the same target.File in questo prodotto:
