Posted September 27, 2018,
by Ian Mayo

We're coming to the end of another new feature. Most of the time Debrief data comes in digital form, captured on another system. But, occasionally it arrives in text form and has to be transcribed. Some users do this within Debrief, others perform the task in a text editor such as Notepad, then save the...

by Ian Mayo

Symbols are used to add value to analysis plots, through giving a visual indication of the vehicle type. In the past, the symbols have been hard-coded in Debrief, but now Debrief supports the provision of vectored symbols in the industry standard SVG format. The first set of symbols is shown below.

New Feature in Development: Support for multiple primary sensors

Posted July 25, 2018,
by Ian Mayo

Analysts have always been able to use Target Motion Analysis (TMA) algorithms to predict missing track data using passive sensor data. Traditionally, this has only allowed use of a single sensor. Now analysts would like to triangulate a track using multiple sensors. This trial release will let you do just that, to perform manual TMA....

New Feature in Development: Manual TMA using sensor measurements from more than one platform

Posted July 24, 2018,
by Ian Mayo

Part of the package of new features to support multi-statics is to allow manual TMA to be conducted using sensor measurements from more than one platform. This video shows how sensor data from two floating sensor buoys can be used to triangulate a straight leg of positional data. The changes to support this have affected...

Sprint 3 - Debrief Lite

Posted July 20, 2018,
by Ian Mayo

Sprint 3 has largely been behind-the-scenes efforts to get ready for some upcoming significant features (especially Debrief Lite). An automated build/test of Debrief Classic is now performed on every commit, and it's now included in every release (rebadged as Debrief Lite). This has allowed us to de-risk the eventual builds of Debrief Lite proper. Debrief...

New Feature in Development: Preparing to Export to PowerPoint

Posted July 19, 2018,
by Ian Mayo

Analysts have some specific needs for their reports. Sometimes they’d like exported images to be in a specific size or aspect ratio. Resizing imported images in word or powerpoint is easy, but if it’s not in the correct aspect ratio the images can get stretched/compressed. Doesn’t look good at all does it? That’s why we’re...

Fine-tuning the Debrief Time Controller

Posted July 12, 2018,
by Ian Mayo

At a recent meeting conducting discovery of what Debrief-Lite should look like, an existing user indicated he really wanted time filtering to be via a dialog box, not by dragging the time filter controls - which is a pain to fine tune in Debrief. Of course, it's already possible to fine-tune these controls to a...

New Feature in Development: Export to PPT

Posted July 11, 2018,
by Ian Mayo

What good is all this analysis if you can’t put it in a report? Many of our analysts use powerpoint to show their teams what they’ve found. Most use cropped screenshots for the task, but we wanted to help them do better. That’s why we’re adding the ability to export scenarios as video files or...

Lightweight Tracks

Posted July 6, 2018,
by Ian Mayo

In today's release we're including a technical demonstrator for Lightweight Tracks. Some analysis tasks require the analysis of traffic passing through the exercise area. This could come from radar, AIS or IFF, and can be hundreds (or even thousands) of tracks. But, in traditional Debrief practice, all tracks sit at the top level of the...

Datasets indexed by non-time data

Posted April 28, 2017,
by Ian Mayo

A shortcoming of the initial backend datastore for Limpet (learn more here: http://limpet.info) was that it could only store datasets that were indexed by time.  This had little impact, since Limpet was only being used for analysis of time-stamped data. But, for the second phase of support for multi-static analysis, Limpet must store data indexed...

by Ian Mayo

Last year's addition of Stacked Charts in Debrief started the movement towards more free-flowing analysis using Debrief.  Stacked Charts allowed the analyst to consider the relationships between any kind of data in Debrief. Traditionally Debrief had a tightly focused data model: platform tracks plus some sensor data.  While new graphical annotations and cosmetic styling of...

We’re launching a new capability for a broader set of analysis. In addition to running standalone  this tool will be seamlessly integrated into with Debrief. Why Do We Need a New Tool? Debrief traditionally enjoys a fixed data model, understanding precisely how to exploit, visualise and process each type of data.  Over the years analysts...

After 20 years of using the same colours, from 1st May 2015, Debrief gets a new color palette. Following the introduction of an alternative background colour set (Debrief’s background was always black before), the decision was made to introduce a new palette set of new colours. This was not only to help with a cleaner...

Abstract Since last Autumn we’ve been working on a significant part of SATC (Semi Automatic Track Construction – see more here). The genetic algorithms in SATC are now quite mature, and do a good job of producing target tracks from bearing only data. But the analysts have had an ongoing chore – the need to...
