RadarPlus® SM1680 "octopus", Phase-Synchronous Octal AIS Receiver Array

INTRODUCING THE RADARPLUS SM1680 The second in a series of disruptive technologies from Shine Micro, Inc.

*Preliminary Datasheet
Nick-named the "Octopus", each of the 8 AIS receivers in the SM1680 provides unparalleled sensitivity and performance. Maximized tracking range is achieved through advanced, real-time signal processing of four synchronized receivers on each AIS channel, using proprietary Shine Micro software and high-accuracy GPS disciplined timing.

The octal array performs packet-by-packet "beam forming", resulting in effective sensitivity increases of 6db or more while also providing noise rejection through "interferer nulling". Beam forming is performed in software, enabling the SM1680 to "point" in multiple directions simultaneously; achieving co-channel rejection performance never before possible.

FEATURES *Preliminary

  • Atomic Standard Accuracy
  • Digital Beam Forming
  • Interferer Nulling
  • Anti-Spoofing Tools
    • Time of Arrival (TOA)

Atomic standard accuracy allows SM1680 arrays many miles apart to form phase-synchronous virtual receivers via Very Long Baseline Interferometry (VLBI). Powerful "anti-spoofing" features, including Time of Arrival (TOA) measurements, allow multiple installations to verify reported vessel positions via Differential Time of Arrival (DTOA).
