Abstract
An avalanche rescue system in which reliable triggering conserves power and permits a high power alarm to be transmitted from a victim to a survivor. Triggering is provided by light sensitive elements on the user, or by a signal transmitted from a survivor. Microprocessor control synchronizes VHF information signal transmission and burst microwave transmission from a victim as well as received signal processing by a survivor. A directional multiple antenna array is switched to provide directional signals displayed to the survivor. A garment is used to affix the system to the person of the user. A unit includes a case and a cover, and the directional antenna array is extended when the cover is opened.
