In this article, we address the filtering problem of a reentry vehicle (RV) using a passive
sensor onboard an aircraft. The passive sensor measures the azimuth and elevation angles …

The goal of this article is to provide a real-time implementable algorithm to estimate the
launch point (LP) of a thrusting object using angle-only measurements. The measurements …

The trajectory estimation problem of a thrusting/ballistic object in three-dimensional (3-D)
space has been previously solved with 2-D measurements (azimuth and elevation angles …

This article considers the problem of estimating the trajectory of a ballistic target in the
reentry phase using 2-D measurements (azimuth and elevation angles) from a moving …

In previous works, it has been shown that the estimation problem of a thrusting/ballistic
object in the three-dimensional space can be solved with two-dimensional measurements …

In previous works, it has been shown that the motion of a thrusting/ballistic object in a three-
dimensional (3-D) space is observable with 2-D measurements from a stationary passive …

This paper considers the problem of estimating the launch point (LP) of a thrusting object
from a single fixed sensor's 2-D angle-only measurements (azimuth and elevation). It is …

It has been shown in previous works that the trajectory of a thrusting/ballistic object in three-
dimensional space is observable with two-dimensional measurements from a stationary …

For a thrusting/ballistic target, works have shown that a single fixed sensor with 2-D angle-
only measurements (azimuth and elevation angles) is able to estimate the target's 3-D …

This paper considers the problem of estimating the 3D states of a salvo of thrusting/ballistic
endo-atmospheric objects using 2D Cartesian measurements from the focal plane array …
