Title: Observability analysis of DOA-TOA target movement analysis
Abstract: Based on the observability theory of nonlinear system,we made observability analysis of DOA-TOA Target Movement Analysis(TMA) for a target moving in a 3-dimentional space with constant velocity.Single-station passive locating based on DOA-TOA canlocate the target by obtaining the change of radial distance from the station to the target because of target moving,which is observed by the station from two TOA surveys.The result shows that: when the change rates of azimuth and of elevation between the observe station and the radiation source are not both zero,the observer can make observation without maneuvering.
