WSS - Intrusion Detection Radar
Field Data
Field trial data illustrates the advanced capabilities of the ECIDR system. The images shown below were from the SeaScan RT radar video display.
High Performance
Detection of targets with RCS of 0.03-0.47m2
In the test twenty-five moored targets were deployed in a 5x5 grid. The targets were plastic spheres, varying in diameter from 0.72 to 2.8 feet, covered with a reflective mesh and sitting directly on the water. The radar cross section of the targets varied from 0.03 m2 to 0.47 m2, representing real-life targets varying in size from a person-in-water (PIW) to a four-man life raft. In addition, drifting targets were deployed and retrieved after each recording trip. The below figures show data with a higher clutter background. This data was collected with a wave height of 3.1 meters. The wind was variable. The image on the left shows spiky clutter with no processing. The image on the right is with the ECIDR processing applied and clearly shows the test targets.
No processing applied, clutter masks targets.
Series 1000 ECIDR processing clearly show small targets in clutter.
