The Color of Radar

Imagine....In dense fog, visual eyesight not an option, sounds nearby becoming distorted, almost reverb echo in a vibration sense.  A foreign atmosphere, dense with condensation of the close to the ground cloud you are totally immersed in. Off in the distance you hear a faint but increasing din of a ship's horn. Exact bearing in relation to your position is but a guess, at the very best. What way is it heading? How fast is it going? Is there movement towards my location? The only technology reliable for this scenario, is Radar. Not just any detection sensor will do in a case such as this, but one that instantly provides you with an urgent piece of information you need for collision avoidance and assessment of risk. That can be found with SIMRAD's Halo Radar with Velocity Track technology.

 

Through pulse compression, Doppler, the system detects targets and displays the data on the Multi-Function Device into the 3 main Categories;  Dead in the Water (including land mass and obstructions),  Diverging, and Converging, the latter of which is obviously the most dangerous. Closest Point of Approach and Time of CPA not calculated, and actually not critical at this initial point in time. Just one very concise and quick piece of important information that makes all the difference in the world to safe navigation. 

 

The new technology advance keenly answers the one main question that absolutely means the most; Is this object observed on the radar dangerous and pose a risk of collision? It calculates this very unique query, within a fraction of time, using... COLOR

 

The simplest of solutions to a problem usually are the best. Color contrast and classification immediately delivers accurate initial situational awareness in a very short period of time. Know what and where your danger areas reside and you are well on your way to a collision free voyage and peace of mind.  

 

How's that for Tactical to Practical. Even better, it is but a software download with the correct configuration of system. This one seemingly small, but extremely significant, change in Radar again makes it the prime sensor for use in situational awareness. Marine Navigation should always rely on more than one sensory input and technique as Bowditch, The American Practical Navigator, Chapter 25 precisely states. 

 

Part of that combination should include  The Color of Radar
