Abstract

The MRTD and MRC end-to-end EO/IR system tests and corresponding models, described in NATO STANAGs 4347-4351, lead to incorrect Target Acquisition (TA) range predictions for modern imaging systems that are 1) usually under-sampled and/or 2) contain complex signal processing. Considerable efforts have been made to develop tests and models that can cope with these highly non-linear properties. This has led to new candidates for inclusion in the standards: the TTP (Targeting Task Performance) range prediction metric (US), the TOD (Triangle Orientation Discrimination) test method (NL), and the MTDP test with the TRM4 model (GE). In the present study, we directly compare TOD, TTP and US tactical vehicle identification performance data for a variety of sensors. The data show that the TOD test pattern is a good representative of the US tactical vehicle set and that the two approaches can be integrated into a single methodology for modelling and testing
