Most research regarding passive radar exploiting `illuminators of opportunity', such as FM radio, has focused on detecting and tracking targets. This study explores adding automatic target recognition (ATR) capabilities to such systems. The ATR algor

Closely-spaced (but resolved) targets pose a challenge for measurement-to-track data association algorithms. Since the Mahalanobis distances between measurements collected on closely-spaced targets and tracks are similar, several elements of the corr

Single-frame measurement-to-track association algorithms that make unique decisions often have difficulty with closely-spaced (but resolved) targets. Such algorithms typically operate on a kinematic measurement-to-track cost matrix. When targets unde

A coordinated flight model for estimating the orientation of an aircraft under track from velocity measurements into an extended Kalman filter (EKF) framework is placed here. In doing so, it makes two contributions. First, the EKF provides a rigorous

Target tracking consists of two main steps: measurement-to-track data association and track filtering. When multiple targets are present in proximity, both steps are more prone to errors. The more the measurement covariances for multiple targets over

A wide variety of radar-based ATR systems and applications have been developed and documented in open literature. As different as these may seem on the surface, they all tend to revolve around four basic steps, labeled in this chapter as the unified

Conventional algorithms for track association (termed "correlation" by convention) employ algorithms which are applied to all sensor tracks at a specific time. The overall value of sensor networks for data fusion is closely tied to the reliability of

The interacting multiple model (IMM) estimator, which mixes and blends results of multiple filters according to their mode probabilities, is frequently used to track targets whose motion is not well-captured by a single model. This paper extends the
