| 摘要 |
A system and method for dual-band detection of incoming threats using an initial passive detection system and a selectively activated active detection system. Advantages include improved threat detection accuracy, reduction of false alarms, and reduced radiation emission from the active system, thereby making the active system more difficult to detect and reducing irradiation levels of users and bystanders. Variations include systems employing passive optical or electro-optical detectors, systems employing active RADAR or LADAR detectors, and systems connected to alarm signal/threat mitigation systems. The system may be configured for use on ground vehicles or small watercraft. Variations of the system may be specifically configured to detect incoming munitions launches.
