1. A ladar receiver apparatus comprising:

  • an array comprising a plurality of photodetectors;

    a plurality of amplifiers, each of a plurality of the amplifiers configured to amplify a signal produced by a corresponding photodetector such that different amplifiers amplify signals produced by different corresponding photodetectors; and

    a circuit configured to (1) process a shot list that identifies a plurality of range points for targeting by ladar pulse shots over time, (2) select a plurality of different subsets of the photodetectors for read out over time based on the range points of the processed shot list, (3) selectively control how power is applied to the amplifiers over time based on the range points of the processed shot list, (4) process the amplified signals from the amplifiers corresponding to the selected subsets of photodetectors, and (5) compute range information for the range points targeted by the ladar pulse shots based on the processed amplified signals.
