Laser imagers, operating at long ranges, have recently become of interest for both military and civilian applications. Systems using large optics and powerful sources are expensive to build and test, and so the image signal to noise and resolution performance should be investigated analytically before testing. However, in many cases, a simulation may provide a better idea of the actual performance. The simulation described here is for a monostatic laser-illuminator angle-angle imager, which is essentially a flash camera. Important phenomena which are modeled include surface reflectivity and glints, diffraction, photon noise, detector noise, and detector size. Laser speckle and illumination beam profiles have not been incorporated into this model. The images resulting from a simulation can additionally answer the question, "What do we do with the image after we get it?", which cannot be addressed by signal to noise or resolution calculations. The model was developed and can be used on an IBM PC, without any special purpose hard-ware designed specifically for image processing.
