Supported analysis for Aegis Ashore Japan, for B41 (radar branch) of the naval surface warfare center Dahlgren division (NSWCDD), working onsite under the Kratos Defense. Primary responsibility involved siting issues. In order to evaluate the relative merit of different sites, the radar firm track range (FTR) was chosen as a metric. A FTR model was developed (and is continuing to be developed) which calculates FTR based on over 50 individual, user defined parameters including FTR algorithm, radar transmitter and receiver parameters, waveform characteristics, target trajectory and signature, site location (full polarimetric clutter is generated from each terrain cell using DTED, DFAD, and calibrated clutter scatterometer database), and detailed antenna pattern generation which can model types of elements, element spacing and geometry for sub-arrays, number of sub-arrays, overall array shape, weighting, and number of phase shifter bits. The code is GUI based, and general enough that it can be used for virtual any radar (not just AEGIS), consisting of approximately 50 thousand lines of MATLAB code. The code was developed solely by me for NSWCDD B41 under the auspices of MDA.
