|Augmenting SeaSonde Networks With Ship Detection
|From their inception, SeaSondes have bucked the
trend of traditional microwave radar systems.
Whereas the latter treat sea echo as clutter and
vessel echoes as signal, SeaSonde software for
environmental monitoring was designed with the exact
opposite in mind.
Now, with SeaSonde real-time vessel
detection software, users can have both. Information
provided includes real-time vessel position, speed,
estimated HF radar cross section and a unique
identifier for tracing through time. Detections and position updates are output at
user-specified intervals, typically every one to four minutes.
Doppler processing allows multiple vessels to be tracked simultaneously even when in close proximity.
|In a network utilizing SHARE™ - enabled frequency sharing, each receiving site
running the vessel detection software can provide independent monostatic,
bistatic or multistatic detections using transmissions originating from itself and/
or other nearby SHARE-enabled SeaSonde Remote Units or bistatic transmitters.
With multiple “looks” from different bearings and radial Doppler speeds,
multistatic network detections allow for increased vessel position and motion
accuracy, larger areas of continuous detections and increased probability of
detection during commingling of vessel and sea echoes or changes in vessel speed
and aspect. Due to the HF Doppler processing, multiple vessels can be tracked
simultaneously, even when in close proximity to one another.
This software package is designed to run in parallel with all other SeaSonde
software on the SeaSonde Remote Unit computer and does not affect traditional
current or wave measurement processing. Vessel detection software can be used
at any SeaSonde operating frequency and performance is subject to local RF noise
conditions. Please contact a CODAR representative for more information.
