Ladar transmitting and receiving system and method

An apparatus for receiving pulses of light from a Laser Detection And Ranging (LADAR) transmitter comprising:

• a tapered fiber bundle;
• a plurality of sensors coupled to said tapered fiber bundle, wherein each sensor comprises a photosensitive region and outputs a photocurrent;
• a plurality of microwave amplifiers, wherein each amplifier is coupled to a sensor and amplifies said photocurrent;
• a plurality of feedback circuits, wherein each feedback circuit is coupled to an input and output of a microwave amplifier and raises the bandwidth of a circuit comprising said sensor and said microwave amplifier;
• and
• a microwave combiner combining said photocurrent from each of said plurality of microwave amplifiers to a combined output.

A method of processing pulses of light from a Laser Detection And Ranging (LADAR) transmitter, said method comprising:

• receiving said pulses of light via a tapered fiber bundle;
• producing a plurality of photocurrents, wherein each photocurrent is produced from a sensor coupled to said tapered fiber bundle and each sensor comprises a photosensitive region to output said photocurrent;
• amplifying said plurality of photocurrents using a plurality of microwave amplifiers, wherein each amplifier is coupled to a sensor and amplifies a photocurrent;
• providing a plurality of feedback circuits, wherein each feedback circuit is coupled to an input and output of a microwave amplifier and raises the bandwidth of a circuit comprising said sensor and said microwave amplifier;
• combining said plurality of amplified photocurrents using a microwave combiner, wherein the number of inputs said microwave combiner accepts is as least as great as the number of microwave amplifiers;
• and
• processing and displaying said combined output.
