Navigation Quality Improvement Using Passive Angle of Arrival Measurement

Navigation and localization are two key issues for many modern mobile applications. Navigation data can be gathered either passively (i.e. by means of INS) or actively (e.g. GPS, Loran). the passive navigation data Usually degrade through the time. On the other hand, the active methods are prune to interference and jamming. In this paper, the passive navigation method is aided by the measured angle of arrival from emitting objects (i.e. radars) at known locations. The results show that in the proposed method in contradiction to many other passive methods, while maintaining the passiveness of the system, using AoA measurement, the quality of navigation data is preserved or even improved through the time.
