1. A laser radar (LADAR) having adjustable operational parameters to accommodate surveillance of a particular site, said LADAR, comprising:

  • a controller;

    a laser source governed by said controller to generate a laser beam pulsed at a pulse repetition rate;

    an optical scanner;

    a first set of optics for guiding said pulsed laser beam from said laser source to said optical scanner;

    a first drive assembly governed by said controller for operating said optical scanner to direct said pulsed laser beam through an azimuth field of regard;

    a second drive assembly governed by said controller for operating said optical scanner to direct said pulsed laser beam through an elevation field of regard;

    a light detector;

    a second set of optics for guiding laser echo pulses returned from said azimuth and elevation fields of regard to said light detector which converts said laser echo pulses into electrical echo pulses representative thereof; and

    a processor coupled to said light detector for receiving said electrical echo pulses and operative to process said electrical echo pulses to generate a range map of the combined azimuth and elevation fields of regard to accommodate surveillance of said particular site.
