SOLAR BLIND ULTRAVIOLET COMMUNICATION SYSTEM FOR UNATTENDED GROUND SENSOR NETWORK

摘要

A wireless inter-nodal communication system which operates in the solar blind ultraviolet (200 nm - 280 nm) and is capable of providing covert non line-of-sight operation. The present invention also encompasses a method for providing inter-nodal communications in an unattended ground sensor network (22, 24, 26, 28 and 30) comprising the steps of making use of line-of-sight ultra-violet radiation with a wavelength within the solar blind region, and in appropriate situation preferably employing wide field-of- view receivers and large transmitter cone angles (82).
