1. the method for a pulsed laser ranging is characterized in that, described method comprises:

  • Send the inceptive impulse signal, and when the rising edge voltage of described inceptive impulse signal reaches voltage threshold, the record start time;

    Receive the former reflected impulse after the described inceptive impulse signal reflex;

    Described former reflected impulse is carried out first to the N time amplify, obtain first to the N reflected impulse;

    Detect and record described first to the N reflected impulse corresponding first to the N amplitude;

    With the preferred threshold voltage magnitude not with first to the contrast of N amplitude, determine preferred reflected impulse, obtain preferred measurement result according to described preferred reflected impulse;

    Described preferred threshold voltage magnitude is preset value;

    Described N is the positive integer greater than 1.
