Analysis of the core content of the standard
This technical report establishes a three-dimensional evaluation system for unmanned aerial vehicle systems (DAA):
Test type Verification target Key indicators Modeling and simulation Obstacle avoidance algorithm verification 24 intersection angle modes + 13 path deviations Equipment testing Sensor performance Radar detection distance 2km+optical recognition 750m Flight test System comprehensive effectiveness Obstacle avoidance success rate at a relative speed of 200km/h
Key points of technical implementation
Typical test configuration
The verification case at the Fukushima Robotics Test Site shows that:
- Medium-sized UAV (Yamaha Fazer G2) equipped with a multi-sensor suite
- Millimeter-wave radar and optical sensor data fusion
- Michibiki high-precision positioning system (error <10cm)
Key performance parameters
According to the test data in Appendix D:
- Minimum obstacle avoidance distance when a manned helicopter approaches at 200km/h: 150m
- Recognition response time of drone at a relative speed of 100km/h: 2.5 seconds
Background of standard evolution
This technical report complements the ISO 21384-3:2023 operating procedure standard:
- 2017: Initial verification visibility test at Fukushima test site
- 2019: Obstacle avoidance at a relative speed of 100km/h
- 2021: Breakthrough in 200km/h high-speed obstacle avoidance technology
- 2024: Formation of a complete test method system
Implementation recommendations
Test solution design
- Prioritize the maneuverability modeling (lateral movement/yaw/lift) described in 6.2.2
- Set the simulation parameter combination according to Table 1
- Equipment-level verification (Appendix B) must be completed before actual flight testing
Risk Control
Special Note:
- The performance of optical sensors decreases by 30-40% in rainy and foggy weather
- At least 500m of safe airspace must be reserved for 200km/h testing
