1. A method of visually displaying a target viewed by an imaging sensor means, the imaging sensor means including pulsed light source means and gated camera means and wherein the imaging sensor means is positioned on an airborne platform and images targets under water and wherein said gated camera means includes a focal plane and an entrance aperture, including the steps of:

  • a) calculating the hypothetical distributions of the number of photons impinging on the gated camera means using a hypothetical physical and optical model;

    b) obtaining actual target data from targets imaged underwater by the imaging sensor means;

    c) processing said actual target data;

    d) delivering said actual target data to an automatic target detection system;

    e) employing said calculated hypothetical distributions in said automatic target detection system by a comparison of said calculated hypothetical distributions with said processed actual target data to thereby improve in the detection of a target viewed by the imaging sensor means; and

    f) visually displaying a target viewed by the imaging sensor means based on the improvement in target detection obtained from step (e).
