ABSTRACT Passive localisation and tracking of a radio emitter is significant interest for both civilian defence applications. Among the existing methods, received signal strength indicator (RSSI)‐based widely used due to its low cost simplicity. However, most RSSI‐based techniques make simplifying assumptions, such as relying on basic path‐loss models presuming has already been detected, overlooking complex environmental effects like shadowing caused by obstacles. These limitations hinder...
