摘要

The portable instrument, to search for bodies buried in an avalanche, has two antenna systems (1,2). The first antenna is operated with a single resonance. The second system has three antennae, orthogonal to each other, operated without resonance, with their signals combined. The receiver is set to a sensitivity of the first or second antenna systems using the first system for longer distances. There is no jump in the signal strength on switching from the first to the second antenna system.
