Systems and methods for detecting electromagnetic signals in a certain interference environment

摘要

Systems and methods for detecting electromagnetic signals in a certain interference environment are described herein. In one embodiment, the electromagnetic signal is an optical signal. The constant interference detector may detect false signal “hits” generated by constant interference, such as bright light saturation, from valid signals. The constant interference detector determines whether there is constant interference for a period greater than the period of the valid signal. In one embodiment, when compared to previously stored ambient light, if the received signal exceeds a programmable threshold for a programmable period, a control signal is generated to notify the next higher network layer of a sudden change in ambient light. This control signal can be used to discard the current return or to process the signal in a different way. The constant interference detector may be a component of the LIDAR system.
