Abstract:
1. A laser radar system for producing a composite image for identifying a non-cooperative target, comprising: (a) a transmit laser for generating a transmit laser beam; (b) a local oscillator laser for generating a continuous wave laser beam; (c) a dual mode detector array having a first portion operating in a coherent mode and having a second portion operating in an incoherent mode; (d) a telescopic lens positioned to simultaneously expand said transmit laser beam and to focus a plurality of reflected transmit laser rays onto said dual mode detector array wherein said reflected transmit laser rays are reflected by said non-cooperative object of interest; (e) a beam splitter positioned between said telescopic lens and said dual mode detector array; (f) a first plurality of mirrors positioned along a transmit laser optical path wherein said transmit laser beam travels to said beam splitter along said transmit laser optical path including said first plurality of mirrors; (g) a second plurality of mirrors positioned along a local oscillator laser optical path wherein said continuous wave beam travels to a diffraction element located along said local oscillator laser optical path, said diffraction element diffracting said continuous wave laser beam onto only said first portion of said dual mode detector array; (h) an electrical signal processor having a first input electrical circuit interface connected to a plurality of output ports of said dual mode detector array, said electrical signal processor having a first output electrical interface; (i) a composite image processing device having a second input electrical interface connected to said first output electrical interface of said electrical signal processor, said composite image processing device having a second output electrical interface; and (j) a user interface having an input connected to said second output electrical interface of said composite image processing device wherein said user interface is connected to an indication medium.
