Paper Abstract

A simple analytical model for the signal acquisition range for a laser guided mortar is presented. The signal consists of a repetitively pulsed laser of fixed pulse duration and fixed pulse repetition frequency. The pulses are detected by a seeker consisting of a quadrant photodiode and a trans-impedance amplifier. Noise is introduced from solar irradiance and from the detector/amplifier electronics. The model maximizes the acquisition range by optimizing trans-impedance amplifier circuit components. A comparison of integrating multiple low energy pulses (MPLD) versus detecting each pulse individually (conventional) is made.
