Towards a Standardised Framework for Evaluating Sensor Performance in C-sUAS Systems

The primary objective of this document is to provide a structured reference for performance evaluation of the different sensor technologies that can be found in counter-drone systems. Standardised parametric models for the sensor(s), drone(s) and the external environment are proposed, with the aim of predicting sensor performance under real-world conditions in representative protective scenarios against hostile drones. In addition to defining these models, the document introduces a set of standardised reference parameter values to ensure consistency, comparability, and practical usability in cases where complete system data are unavailable. A set of clearly stated assumptions will therefore be formulated, dictating the boundary conditions for which the selected model can or cannot be used. The advantages of the parametric and standardised approach are numerous. For example, it makes it straightforward to compare the performance of different systems during a tender process, given that a set of common parameters must be known and provided (supplier data or standardised default values) for each system. This modelling approach also reduces the costs linked to practical field tests/deployment. Note that the focus is placed on developing simpler models to ensure ease of use and practical applicability, while maintaining an acceptable level of reliability and accuracy. The framework presented in this work is strictly oriented towards the defensive sensing function of C-sUAS systems and does not address effector design, kinetic engagement or offensive sUAS capabilities.
