Paper Abstract

A receiver with high dynamic response and wide control range are necessary for a laser radar system. In this paper, an automatic gain control scheme for laser radar receiver is proposed. The scheme is based on a closed-loop logarithmic feedback method. Signal models for pulse laser radar system are created and as the input to the AGC model. The signal is supposed to be very weak and with a nanosecond order of pulse width in the light of the property of the laser radar. The method and the simulation for the AGC will be presented in detail.
