SADAR® – Setting the global benchmark for State-of-the-Art Awareness

Selected assets demand advanced intrusion detection and movement monitoring solutions and enhanced data quality on threats with expanded intrusion detection ranges. SADAR® takes perimeter awareness to the next level with greater control in threat tracking, identification, classification and reporting. Through seismic-acoustic detection and ranging capability, Quantum’s QA-100 offers information about both inside and outside the awareness zone for assets, large or small.

Detect, Classify and Track Threats

Our SADAR® system delivers previously unobtainable monitoring fidelity through seismic-acoustic detection and ranging capability. SADAR® autonomously detects, classifies and tracks targets from a distance.

Seismic-acoustic detection and ranging capability far exceeds human senses and tracks threats through obstacles that hinder line-of-sight security systems such as fog, forests, water, physical barriers, and the horizon.

The individual Smart Sensors detect ground vibrations and deliver them to a central Smart Node where the signals are combined and processed together to deliver extended system features. Based on its analysis, the system generates specific, actionable alerts.

The number of sensors and configuration for any seismic-acoustic detection and ranging application are a function of the asset being secured.

How Does SADAR® Work?

With a function similar to that of RADAR or SONAR, a SADAR array comprises 8 to 32 small seismic sensors in a pattern, each buried underground. With the seismic acoustic detection and ranging capability, the sensors work in a coherent way to increase the signal to noise ratio of detected vibrations and to determine the direction to the source.

Vibrations in the earth are converted to signals by each sensor and are immediately combined with other sensor signals and automatically analyzed by the node. The sensors don’t require line-of-sight with the signal source to detect it. When the system determines that the vibrations are from a programmed signal of interest, the node immediately transmits an alert message to the user interface, along with information on the direction from the node to the signal source. Algorithms for other signal sources of interest, such as motorboats and powered aircraft, are available as custom options.

Multiple SADAR arrays detecting the same source and indicating direction to it will “cross beams”, localizing the position of the potential threat and tracking its movements. The standard monitoring station software supplied with the product is normally installed on the customer’s user interface. In a map view, coded icons display at the node’s position. These icons indicate the state of health, and information on alerts. When an alert is generated, a color-coded line extends outward from the node’s position in the direction of the signal source, enabling real-time tracking of the movement of the potential threat.

Seismic Acoustic Detection and Ranging Border Tunneling Detection Technology

SADAR® is proven to be a ground breaking tunneling detection and location capability. Not only can subsurface activity be located, but the source of energy can be classified as well. This is done using seismic acoustic detection and ranging border tunneling detection technology.

SADAR® is a volumetric array of several dozen buried sensors, which is roughly 5m or less in diameter. SADAR® uses seismic “beamforming” techniques to determine the direction of arrival of a source’s signal, and automatically generates alert message information when a signal of interest is detected. A set of classification algorithms uses characteristic features extracted from each type of waveform to determine each signal’s classification. In operation, a SADAR® array automatically and in real-time detects, classifies, and “follows” of signals, which are displayed over time as a heat map on a user interface.
