Magnetic and low frequency
electromagnetic sensors provide opportunities and
challenges for detection, tracking, and classification
of various non-cooperative targets. An array of
sensors configured in a suitable network provides
several advantages. A multiplicity of sensors allow
improved signal processing and noise cancellation,
resulting in improved range of detection. A networked
architecture also allows detection, localization,
tracking, and classification.
Practical use of such a system
will require optimization in terms of relevant parameters
such as, specific applications, type of sensors,
sensitivity, power, cost, deployment, networking,
signal processing, computational load, telemetry,
node and cluster formation, etc. Such optimization
will require thorough experiments under field conditions.
We have developed a networked magnetic
array based system for field test and field demonstration.
The system provides real-time acquisition and analysis
of the signals from an array of magnetic sensors.
The targets are detected, tracks established, pertinent
features of the targets are classified, and displayed
in real-time. We describe the system and the issues
associated with such a system as well as possible
improvements to the system.
