SeaSonde Multi-Static Data Processing Software
Package
(single-use license)
CODAR Product Code: SSDA-ES100
Product Description:
The multi-static data processing software package enhances the conventional
backscatter "Current" tool that
produces radial velocities from SeaSonde echoes, by enabling processing of
sea echoes from separated transmitters.
The result is a set of bistatic elliptical files for each set of echoes that
originate from synchronized transmitters
included within radar range. For example, if three transmitters are within
range and synchronized -- as
well as that station's transmitter -- then four sets of current scalar-velocity
estimates are produced. These follow
the same LLUV formats (latitude/longitude/u/v) as standard backscatter radials,
so that subsequent algorithms
will recognize and utilize them, including combining tools to get total vector
maps. This ensures that the outputs
are backward compatible with existing downstream algorithms.
The advantage of augmenting to multi-static operation by employing the signals
from additional transmitters is
the improved total-vector current-map coverage, both in extended area as
well as more accurate vectors within
the included area.
Examples of radial velocity vector maps from conventional backscatter
method (left)
and a bistatic elliptical map (right) both simultaneously produced
at same SeaSonde
receiver, utilizing multiple transmitter signals and calculated with
the multi-static data
processing package.

Technical Specifications †
Requirements:
Valid Existing Software Licenses: SeaSonde remote unit data
processor (computer) comes with a valid basic
SeaSonde remote-unit radial-suite processing package with a single-user software
license. By procuring
the new multi-static software package, elements of the existing processor
are replaced and an additional
single-user license is included, enabling proper operation of the new multi-static
capability.
Radial Suite software version: The radial suite software package running
on the computer should be at least
Release 6 or updated to our latest version prior to installation of multi-static
data processing package.
Computer: PowerPC or Intel running on at least OS X 10.4.11 with 512kB ram
(10.5 preferred with 1GB ram)
Special Setup: Recommend use of measured antenna pattern with 1 degree spacing.
Installation & Activation
When this software package is purchased, it is keyed and tied to a firmware
chip that CODAR will supply. This
chip resides in the SeaSonde Receiver chassis, on a USB hub. This allows
security by ensuring that the singleuser
licensed tool will run only with that unit, providing authorization to the
owner and ensuring protection
against theft or copying for use on unlicensed systems.
