Counter UAV Design Assessment

Counter-Drone Technology, known as Counter-UAV, Counter-UAS or CUAS, refers to the denial or disruption of unmanned aircraft. While Unmanned Air Systems provide a multitude of benefits, the threat of UAS can be a threat to civilian, commercial and military assets and installations.

WEMEC have been working in the Counter-UAV arena, assisting with design and assessment of mobile and fixed C-UAV systems. Our focus has been on both system effectiveness as well as the impact to the surrounding environment, including collateral damage, RF fratricide, and EMF exposure.

Safety is of critical importance with use of these systems due to the congested use environments; to this end, WEMEC have assisted in the design to ensure compliance with European & UK requirements. A sample of the assessments and certification already performed include:

  • Occupational RF Exposure – Mandatory requirement Directive 2013/35/EU on the minimum health and safety requirements regarding exposure of workers to the risks arising from physical agents (electromagnetic fields)
  • Public RF Exposure – The International Commission on Non-Ionising Radiation Protection (ICNIRP) define exposure limits and it is the UK policy to comply with 1998 ICNIRP guidelines as directed by 1999/519/EC Council Recommendation of 12 July 1999 on the limitation of exposure of the general public to electromagnetic fields (0Hz to 300GHz).
  • EMC Directive 2014/30/EC – The electromagnetic compatibility (EMC) Directive 2014/30/EU ensures that electrical and electronic equipment does not generate, or is not affected by, electromagnetic disturbance.
  • Defence Standard 59-411:2019 Issue 3; Electromagnetic Compatibility Part: 03: Test Methods and Limits for Equipment and Sub Systems
  • EN 50566:2017 – Specific Absorption Rate for hand-held and body mounted devices in close proximity to the human body
