• Abstract: Monocular Passive Ranging (MPR) may allow accurate target range estimation even when active measurements or multiple views are not possible. Due to the inherent nature of the MPR solution. the uncertainties may degrade the utility of the range estimate. Proper spectral band selection is essential for error minimization. The study goes beyond the traditional CO2 red spike band for MPR. Featured in the current analysis are the following absorption bands: O2 at 0.76 microns CO2 at 2.0 and 4.3 microns and Ozone at 4.7 and 9.6 microns. More importantly, a sensitivity analysis procedure is presented that both minimizes these errors and provides an uncertainty assessment of the range measurement. The result is an improved ranging capability and a more accurate characterization of the intervening atmosphere. The solution technique is applied to an actual HALO/IRIS measurement (Black Brant). However, the MPR software is designed to provide real-time range estimations and atmospheric compensation. A research version of the code has been developed to support integration of this technology into the HALO/IRIS upgrade.
