Abstract
Some embodiments of the current invention relate to finding and identifying a transmitter. In some embodiments, two antennas are separated by an offset, and/or receive a single signal. Optionally, a processor determines a direction to the transmitter of the signal. For example, the determination may be based on a phase difference between the response of the two antennas. Optionally, the device further includes an identification module that may determine an identification associated with the transmitter. For example, the system may be used to find a particular object or person and/or to differentiate between a friend and a foe.
Claims17
A system for preventing friendly fire casualties comprising:
- a transmitter with a unique identifier signal indicating a friendly object;
- a direction finder mounted on a weapon said direction finder configured receive a signal transmitted by said transmitter and to determine a direction to said transmitter based on said signal;
- an indicator configured to warn a user when said weapon is directed toward said transmitter;
- and
- a processor configured to analyze signals from said direction finder in real time and to record signals for post processing, said processor further configured to recognize a problem with identification of the friendly object from the unique identifier signal, wherein the problem includes the unique identifier signal belonging to an object that is not supposed to be located at a location of said transmitter.
A method for preventing friendly fire casualties comprising:
- positioning a transmitter with a unique identifier on a friendly object;
- transmitting, with said transmitter, a signal including a unique identifier of the friendly object;
- receiving said signal transmitted by said transmitter, said receiving via a direction finder mounted on a weapon;
- determining by said direction finder a direction from said weapon to said transmitter and an identity of said friendly object based on said signal;
- indicating to a user of said weapon when said weapon is pointing in the direction of said friendly object;
- analyzing signals from said transmitter in real time and recording signals for post processing;
- recognizing a problem with identification of the friendly object from the unique identifier signal;
- and
- verifying an identification of an authorized party using the transmitter and indicating in said signal transmitted by the transmitter when the user not verified.
