Apparatus and methods for snow and ice detection and removal on a communication antenna
Abstract:
A method of detecting and removing ice and/or snow on a communication antenna is presented. In the method, environmental data indicating at least one current environmental condition is received. An optical signal is transmitted from a signaling structure of the communication antenna toward a reflecting surface of the antenna. The optical signal is received at the signaling structure upon returning from the reflecting surface. The returning optical signal is then processed to determine at least one characteristic value of the returning optical signal. The reflecting surface is then heated if the environmental data indicates that ice or snow accumulation on the communication antenna is possible, and the at least one characteristic value of the returning optical signal is outside a predetermined range.
