System and method for friend or foe identification
First Claim
Patent Images
1. A system for use in identifying one of an unmanned ground vehicle and an unmanned aerial vehicle, the system comprising:
- a signal emitter associated with the unmanned vehicle, the signal emitter including a housing having an aperture and at least one quantum cascade laser within a hermetically sealed environment within the housing and a driver configured to cause the quantum cascade laser to emit a signal having a wavelength between approximately 2 μ
m and approximately 30 μ
m,wherein the quantum cascade laser is configured to emit the signal from the aperture, wherein the signal is detectable to identify the unmanned vehicle as friendly at a distance from the signal emitter greater than approximately 1 meter, and wherein the housing is configured to allow air from outside of the unmanned vehicle through the aperture so that heat generated by the quantum cascade laser is transferred from the hermetically sealed environment into the moving air during movement of the unmanned vehicle to cool the quantum cascade laser.
