What Makes ARS the Best Performing System?
After 15 years deploying many radar systems around the world using different radars for different applications, the SRI team understands what attributes in a radar make it most effective in what environments. In airports, the following attributes are most important and will determine the effectiveness of the system. SRI has developed the turn-key ARS with these attributes, resulting in the most effective system for airports. Details on these attributes can be found in our News Reel article titled “Selecting a Ground Radar for Airport Perimeter Security”.
360-degree coverage to maximize the coverage of each unit High frequency and high resolution to detect objects close to stationary objects
FMCW processing means objects are detected an any direction or if stopped Processing software classifies objects and applies rules so that only threats cause alarms.
The ARS radar has been widely deployed in Europe and has now been approved by the FCC for use in US airports with no license. A turn-key delivery model means the system is delivered and up and running on the same day. SRI provides full support and offers extended warranty through the 10-year service life of the system.
How do You Measure the Performance of a Surveillance System?
ARS is now available in ranges that nominally track people to 300m, 500m, 1000m, or 1500m. These are not best-case maximum ranges; they are nominal ranges in grass for a person. Ranges for vehicles and aircraft are much higher, and people have been tracked at much longer ranges in testing.
Tracking is not simply a blip on the screen. The radar is detecting, the software is processing, and the camera is following. Objects do not have to be traveling to or away from the radar as with Doppler systems; they are tracked in any direction and at any speed, including stopped.
In field trials at US commercial airports, hundreds of tests resulted in near 100% tracking and near 0% false alarms. In addition to low false alarms from the tracking function, the system classifies objects and applies user defined rules to ignore normal operations and only alarm on potential threats. The result is true surveillance automation that only requires an operator to respond if a potential threat exists.
Safe Skies Alliance is an independent evaluator of the performance of perimeter security technologies for the FAA. They have conducted over 80 comprehensive evaluations of various technologies in the past 5 years, each of which lasted from days to months.
