A system and method for controlling movement of a machine or a portion of the machine. The method comprises processing a waveform based on detected reflected light and a derivative of the waveform. The waveform includes a return. The method further comprises classifying the return as a phantom target or a non-amorphous target based on the result of the processing, and controlling movement of the machine or a portion of the machine based on the result of the classifying the return.

LIDAR waveform classification

An engine control system, dredging system, and a method for controlling torque output of an engine. An engine control system controls torque output of an engine. At least one sensor is coupled with the engine. The sensor monitors and transmits operating data of the engine. An electronic device coupled to the sensor is operable to control the engine as a function of the transmitted operating data. The engine is controlled by the electronic device to operate substantially at a predetermined torque limit over a predetermined range of engine speeds, by determining and regulating an amount of fuel to the engine. Alternatively, the engine is controlled by the electronic device to operate substantially at, and between predetermined upper and lower torque limits over a predetermined range of engine speeds, by determining and regulating an amount of fuel to the engine.
