Passive bearings-only target motion analysis (BO-TMA) is to estimate the position and velocity of a target from bearing measurements with corrupted noise obtained by an observation platform.
Temperature measurements and its long-period observation will provide reliable basic data for geothermal and geodynamical study of the ultra-high pressure metamorphic belt.
