Abstract:
The subject matter discloses a method for generating a directional context to measured environmental condition values, comprising measuring by a Target at least one environmental parameter with at least one Environmental Sensor in the Target, conducting direct wireless communication between the Target and a Looker device, transmitting said measured environmental data by the Target, receiving environmental data at the Looker device from the Target, determining at the Looker device a relative location of the Target versus the Looker device, associating at the Looker device said environmental data with said relative location, generating at the Looker device a directional indication by the Looker according to the received environmental data, said indication associates the Target's relative location with the received environmental data
Abstract:
The subject matter discloses a method to determine a relative direction of a target RF transmitter, performed by a direction finding (DF) system comprising at least a pair of antennas having an electromagnetic-absorbing material between them, comprising conducting wireless communication between the target RF transmitter and each one of the antennas of the DF system, measuring the signal strength of the target RF transmitter received at each antenna, calculating the difference between the signal strength measured at each one of the antennas in the pair, and determining a relative direction of the target RF transmitter to be is the direction of the antenna within the pair of antennas in which the stronger signal was measured.

Abstract:
The invention relates to a method for determining by a direction finder (DF) the direction to a Target, which comprises^ (a) providing an antenna at said DF, and an array of antennas at the Target; (b) providing a compass at each of said DF and said Target, for determining the azimuth of the DF Heading and of the Target Heading, respectively, with respect to the North; (c) providing at said DF a look-up table which describes n antenna patterns, one per Transmission Mode that may be used respectively at the Target; (d) sequentially performing x Transmission Modes from the Target, each time using another pair of antennas, and during each of said Transmission Modes intentionally, and in a controlled manner attenuating a reception signal at the DF until a loss of communication, and recording the respective attenuation levels; (e) based on said x recorded attenuations levels and said look up table, determining by the DF the direction from the Target to the DF; and (f) receiving at the DF the azimuth of the Target, and based on (i) said determined direction from the Target to the DF (ii) azimuth of the Target; and (iii) azimuth of the DF; calculating by the DF the direction from the DF to the Target.
Abstract:
The present invention relates to a method for determining the direction to a target by a direction finder, which comprises: predefining a direction axis as a 0° direction; first and second pair of antennas arranged such that a first line connecting between the first pair of antennae defines a 0°-180° axis parallel to said direction axis, and a second line connecting said second pair of antennas defines a 90°-270° axis perpendicular to said direction axis; generating a 0° antenna pattern and establishing a wireless communication between the direction finder and said target; attenuating the wireless communication signal until lost and recording the attenuation value; generating a 180° antenna pattern using said first pair of antennas, and establishing a wireless communication between the direction finder and said target; attenuating the wireless communication signal until lost, and recording the attenuation value and concluding a true direction to the target.
