Digital signal processing method and implementation for pulse laser rangefinder


The laser echo pulses of a Pulse Laser Rangefinder are narrow, weak and low SNR (Signal-to-Noise Ratio) signals. Digital signal processing method was presented for such signals to improve SNR. A digital signal processing circuit of a Pulse Laser Rangefinder was designed, based on DSP (Digital Signal Processor) and CPLD chips. The algorithms of digital… (More)
