Real-Time Obstacle Detection Ladar System Utilizing Ultra-Sensitive APD Array

Not Available Sensor developers require the capability to easily generate scenes used to test sensor designs. As with model atmospheres used by MODTRAN/MOSART, the community recognized the need for model terrain materials with full optical/thermal specifications. This database would give users the ability to create realistic surfaces, complete with expected spectral responses at other wavelengths and environmental conditions. We propose to develop the underlying database(s) and software to use in conjunction with multiple radiative transfer models; thereby providing an enhanced surface rendering tool for simulation packages. Included will be a reclassification scheme of standard land surface types for the earth based on the abundance/importance and intrinsic physical properties. The baseline for the Master DB will be the IGBP/MODIS/NPOESS schemes. Overlying this database will be a software module that will allow the user to reclassify categories as needed or select specific categories or groups of categories. The Standard Surface Material Classifier Software will then create a dynamic, overlying Terrain Materials Database. This information is passed to surface rendering model(s) selected by the user. Surface-specific BRDF's will be calculated, if required by the selected Radiative Transfer Model(s). The user will also be able to specify viewing/illumination geometry and vary some environmental parameters.
