Full title and description

ISO/TR 23267:2024 — Experiment results on test methods for detection and avoidance (DAA) systems for unmanned aircraft systems. A technical report summarizing experimental verification of test methods for DAA (detection-and-avoidance) systems intended for UAS, with emphasis on radar and optical sensor architectures and on methods used in modelling, equipment and flight tests.

Abstract

This technical report presents the results of experiments and validation activities for candidate test methods used to assess detection-and-avoidance (DAA) systems for unmanned aircraft systems (UAS). It documents modelling and simulation approaches, laboratory/equipment tests and flight trials used to evaluate sensor performance (radar and optical), detection/recognition ranges, tracking, latency, false alarm behaviour and avoidance outcomes. The report is intended to provide evidence and practical examples to support the development and validation of normative requirements for DAA systems.

Scope

ISO/TR 23267 reports on tests performed to demonstrate and validate test methods for detection-and-avoidance systems used by unmanned aircraft systems when interacting with other objects including crewed aircraft. The report covers test-subject descriptions, modelling and simulation approaches, equipment bench tests and flight-test procedures, plus evaluation criteria for sensor performance and for complete DAA system behaviour. It focuses on practical experimental results that can inform the formulation or refinement of normative requirements for radar- and optical-based DAA architectures and for conformance test methods.

Key topics and requirements

• Overview of DAA system architecture (radar + optical sensor configurations and sensor role allocation)
• Test-method categories: modelling & simulation, equipment/bench testing, and flight testing
• Test-item definitions and instrumentation requirements for sensors and UAS platforms
• Performance metrics: detection and recognition distances, tracking accuracy, latency, probability of detection, false alarm rate and classification reliability
• Evaluation procedures for avoidance decision logic and verification of avoidance outcomes
• Example encounter scenarios and test sequences representative of UAS-to-aircraft and UAS-to-object interactions
• Recommendations for data collection, repeatability and repeat-test reporting to support standards development
• Guidance to support translation of experimental evidence into normative safety and quality requirements

Typical use and users

The report is aimed at standards developers, regulators, test laboratories, UAS and sensor manufacturers, systems integrators, and researchers working on DAA for unmanned aircraft. It is used to inform normative requirements, to design conformance and verification campaigns, and to guide R&D and product validation for DAA-capable UAS intended to operate safely near other aircraft and in complex operational environments.

Related standards

ISO/TR 23267 is linked to and intended to support the development and application of related normative documents, notably ISO 15964 (Detection and avoidance systems for uncrewed aircraft systems) and ISO 21384-3 (Unmanned aircraft systems — Part 3: Operational procedures). The technical report provides experimental evidence and example test methods that can be referenced when applying or implementing those standards.
