LADAR enabled impact mitigation system

An active vehicle suspension system comprising:

• a vehicle with a ladar sensor mounted thereto,
• a suspension actuator, the suspension actuator attached to a suspension member of at least one wheel of said vehicle, and the suspension actuator also attached to a chassis of said vehicle, and the suspension actuator adapted to actively raise or lower said wheel in response to a control input,
• a suspension control processor providing said control input,
• and said ladar sensor comprising;
• a receiving lens assembly,
• a laser transmitter and said laser transmitter with a modulated laser light output and a diffusing optic for illuminating a scene in the field of view of said ladar sensor,
• a two dimensional array of light sensitive detectors positioned at a focal plane of said receiving lens assembly, each of said light sensitive detectors with an output producing an electrical response signal from a reflected portion of said modulated laser light output,
• a readout integrated circuit with a plurality of unit cell electrical circuits, each of said unit cell electrical circuits having an input connected to one of said light sensitive detector outputs, each unit cell electrical circuit having an electrical response signal demodulator and a range measuring circuit connected to an output of the electrical response signal demodulator, the range measuring circuit further connected to a reference signal providing a zero range reference for the range measuring circuit,
• and a detector bias circuit connected to at least one voltage distribution grid of said array of light sensitive detectors,
• a digital processor connected to receive an output from the range measuring circuit and provide an input for the suspension control processor,
• and a temperature stabilized frequency reference connected to the digital processor.
