Abstract
The Maritime Forces Pacific (MARPAC) Operational Research Team requires the development of models of current and potential coastal surveillance platforms. These models need to be developed in the Systems Tool Kit (STK) Professional software to ensure required fidelity and reliability of the model. Several of these coastal surveillance models include the modelling of the RADARSAT-2 (RS2) satellite. Discrepancies in the RS2 modelled ground swath were previously found in [1] when comparing the results of the RS2 satellite object’s sensors in the STK models and real-world Keyhole Mark-up Language (KML) swaths of ground passes. The objective of this task was to develop and implement a process to automate the application of STK temporal constraints and display time interval files such the RS2 sensor beam footprints’ coverage is aligned with swath geographic coordinate data from one or more RS2 KML input files. This process was implemented in MathWork’s MATLAB R2015a scripting language. The MATLAB script made use of the STK software package version 11.1.0, STK Connect commands and STK Coverage Analysis. The MATLAB script and functions were successfully implemented to generate the coverage aligned STK RS2 interval files. A set of test STK scenarios that made use of RS2 temporal constraints display time files were generated for four sample timeframes, each of one week in duration, from a series of Technical Authority (TA)-provided RS2 KML files.
