Mutual-aided target tracking and identification (ID) schemes are described by exploiting the couplings between the target tracking and object ID systems, which are typically implemented separately. A hybrid state space approach is formulated to deal with continuous-valued kinematics, discrete-valued target type, and discrete-valued target pose (inherently continuous but quantized). We identify ten possible mutual aiding mechanisms with different complexity in different levels. The coupled tracker design is illustrated within the context of using ground moving target indicator (GMTI) and high-range resolution radar (HRRR) measurements as well as digital terrain elevation data (DTED) and road maps. The resulting coupled tracking and ID system is expected to outperform the separately designed systems particularly during target maneuvers, for recovering from temporary data dropout, and in a dense target environment. We simulate HRRR ID support information to assist in pose-model selection of an Interacting Multiple Model (IMM) tracker using GMTI measurements.
