#EMDAR

Evolution: Needle in a Haystack

This EMDAR evolution involves tracking a stationery TSMO that begins just on the edge of EMDAR range. It is intended to provide training and competency evaluation on interpretation of waterfall data, operation of contacts board and operation of narrowband EMDAR.

EMDAR Operations

This course provides an introduction to tactical sensor systems (EMDAR), including underlying theory, basic interpretation techniques and console operation.

Narrowband EMDAR

Narrowband EMDAR uses the same passive EM detection system as broadband EMDAR but is far more directional, focussing on a very limited area of space.

EMDAR Console

The EMDAR console allows the tactical team to analyse and manage data from the vessel's EM detection arrays, which provides data to identify and locate other vessels in surrounding space.

The console is made up of two panels. One provides displays sensor data, while the other allows users to manage the interpretation of that data (in the form of identifying 'contacts').

Component Panels

The console's component panels are:

EMDAR Waterfall Module

Typical EMDAR waterfall console layout with four modules.  Note the blue target lines displayed on the port and aft modules.The EMDAR waterfall module presents EMDAR detections on a distinctive visualisation that provides historical context and allows pattern analysis to help identify possible contacts.

Waterfall Module Configuration

Configuration settings for each EMDAR waterfall module are stored as applet data in JSON format.

Parameters

VESSEL ID: This is the UID of the vessel operating the underlying EMDAR system

ARRAY: This is the operating direction relative to the ship of this instance.

Options are:

  • fwd
  • aft
  • stbd
  • port

ORIENT: This is the orientation group (see below) that this instance belongs to.

Options are:

Contact Board Module Configuration

Configuration

Script Path: /view/nav/contacts/contactBoard.js

Function: dispConBoard(instance)

Display Modes

The contact board has two main display modes:

Active Mode (Mode 0)

This mode allows an operator to add and manage contacts. Typically there is only one active contact board.

TL-EMD02 Panel

This panel works in conjunction with TL-EMD01. It is dominated by the Contact Board module (in active mode), which allows users to add and manage EMDAR contacts.

TL-EMD01 Panel

This panel works in conjunction with TL-EMD02. It displays data from the vessel's broadband EMDAR arrays.

EM Output Profiles

Several major vessel systems output EM radiation at detectable levels. MIE (impulse) engines output significant amounts of EM across UV, IR and magnetic bands, for example.

Each emitting system has an EM Output profile which determines how much EM is output at a given power or operating level, across all five EM bands.
