Abstract:

The influence on the location performance of the attitude vibration of a moving observer, which utilizes a long baseline interferometer （LBI） structured passive location system, is discussed. Because of the vibration, the rate of phase difference change (RPDC) method is not feasible any more. The parameters of rate of DOA changes should be adopted. A range parameterized least square (RP-LS) method is proposed to estimate the rate of DOA changes and locate the emitter under the 3-D circumference when the attitudes vibrate.
