Abstract

The RF system for preventing hunting accidents comprising RF interrogator mounted on the firearm or hunter'"'"'s hat and RF transponder attached to hunter'"'"'s hat, wherein directional pattern of antennas of the hat-mounted interrogator is directed along the line of view of the hunter so matching with sightline of hunter'"'"'s rifle; and RF transponder, which, to cover directional pattern of 360 arc degrees in azimuth, contains a number of RF transceiver evenly attached to the hunter'"'"'s hat in horizontal plane and connected to the single electronic unit. The system provides alert information about “friendly targets” that could be under fire, such as other hunters or persons equipped with said transponder; and if they are, the system develops alert signal: “Do not shoot”.

Claims

9-1. The RF system of claim 1 comprising the interrogator and the transceiver, wherein, to eliminate possible interference between received response signal and reflected signal, the request signal sent by said interrogator is modulated by frequency exceeding threshold frequency of human ear;

so said reflected signal received by said interrogator becomes not hearable.
