This paper considers the measurement extraction for a point target from an optical sensor's
focal plane array (FPA) with a dead zone separating neighboring pixels. Assuming that the …

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 …

The state of a thrusting/ballistic object moving in a 3-D space can be determined uniquely by
a 4-D parameter vector (launch azimuth and elevation angles, drag coefficient, and specific …

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 …

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 …

Target tracking has been under extensive investigation for the past several decades. It has
wide applications, such as defense, computer vision, robotics, etc. Optical sensors are …
