Summary

The Performance Assessment for Tactical Systems (PATS) software
tool was developed to provide a means of assessing multistatic
sonar performance. The tool allows a user to specify a model
environment and sonar system configurations, and the potential
performance of the multistatic sonar system is characterized by
combining acoustic propagation model results with statistical
analysis. The software is primarily written in Matlab. The
output of a separate acoustic model is read into Matlab and the
results are used in conjunction with the sonar equation to allow
for calculation of sonar system performance based on the
estimated signal excess at each model grid point. There is a
requirement to restructure program variables, improve program
flow, and implement sonar performance metrics.

Requirement

The Matlab portion of the PATS software consists of the main
program (4500 lines of code), 115 functions of varying length
(several have up to 500 lines of code), and 30 auxiliary scripts.

The following tasks are required:
1.	Restructure program variables:
	a. 	replace hard-coded variable names with appropriate vectors,
matrices, and 				structures in order to maximize the use of the
indexing capabilities inherent in Matlab and 			reduce the
number of variables passed on each function call
	b.	change object data types to structure data types where
appropriate
	c.	remove "orphaned" variables that are no longer needed
2.		Improve program flow:
	a.	change all instances of hard-coded, operating
system-dependent paths in order to 			make the code
platform-independent
	b.	re-use code in loops or functions, as appropriate, resulting
in consistent data 				manipulation, using the capability
provided by Task 1a
	c.	move the figure generation code out of the main program and
into functions
	d.	improve automatic figure generation capability (details to
be provided by 					Scientific Authority; may include, e.g.,
rearranging sub-figures, forcing uniform axis 			limits across
figures, adjusting font sizes, correcting titles and axis labels)
3.		Improve sonar performance metrics:
	a.	correct the existing implementation of the area coverage
metric, 
	b.	add calculation of other sonar performance metrics as
determined by the Scientific 			Authority.

The task numbers indicate the priority level, with Task 1 having
the highest priority. In the event that not all tasks can be
completed, consultation with the Scientific Authority will be
required to prioritize the requirements. Additional details of
each task will be provided by the Scientific Authority following
contract award.

Proven experience in the production of efficient Matlab code is
required as detailed in Annex C, Evaluation Criteria. In
addition, an understanding of basic physics and numerical
modelling is required, while familiarity with underwater
acoustic propagation modelling would be an asset.


The requirement is subject to a preference for Canadian goods
and/or services.

Bid evaluation will be based on point rated evaluation criteria.
 The responsive bid, within the current funding limitation of
$40,000.00, applicable taxes extra, for the currently funded
work, with the highest total overall points will be recommended
for award of a contract.

The work will begin immediately upon contract award and will be
completed by 31st March 2015.

The solicitation document contains complete details on the
requirement and the bid evaluation and contractor selection
methodology.
