Observability analysis of single passive observer
Zhou Yiyu, Sun Zhongkang · 2002
In this paper observability of single passive observer for target motion slate estimation is discussed. Passive observation systems are divided into bearing, time of arrival, Doppler, bearing and time of arrival, bearing and Doppler observation systems. For every type of systems, observability is analyzed in common observation model. The approximate equivalent relation in systems between time difference of arrival and Doppler is shown by comparing their observability degrees.
