Asynchronous Passive Multisensor System Observability With Unknown Sensor Position
Itzik Klein, Yeshaya Lipman, Yaakov Bar‐Shalom · IEEE Transactions on Aerospace and Electronic Systems · 2017
A method is derived for forming composite measurements when the line-of-sight measurements from multiple sensors are asynchronous and the position(s) of one or more passive sensors is (are) unknown. Using the composite measurement, the target position, velocity, and unknown sensor location are estimated. Additionally, general analytical observability conditions are derived.
