Track Evaluation of GSM based Passive Radar: Model vs. Real-World Results

Closing the feedback loop has proven essential for performance improvement and enhancing system reliability in a number of applications. Track evaluation addresses these goals by investigating system influences and analyzing discrepancies between expected and actual operation. Developing a model of a passive radar system which approximates its operational capabilities is therefore not only essential for performance prediction and pre-operational analysis but offers the opportunity for further system improvement. In the following, we assess the fit of a passive radar model to real-world data to investigate if it provides a reasonable representation of the observed results. There, we show that the detection probability model as well as the estimated lower bound on achievable estimation accuracy, where we utilize the Cramér-Rao Lower Bound (CRLB), give a reasonable approximation of real-world results collected by a passive radar system which utilizes Global System for Mobile Communications (GSM) signals.
