(Yicai Global) Aug. 18 -- Production has started on an anti-drone electromagnetic shield drone maker Chongqing Yidong Technology Co. (CYT) developed.

The shield can disrupt over 90 percent of consumer and commercial drones in the Chinese market.

The electromagnetic shield operates in a manner similar firing live ammunition as it uses electromagnetic interference to repel or bring down intruding unmanned aerial vehicles (UAV), the official Xinhua News Agency reported.

The small-size, lightweight product uses rechargeable lithium batteries making it portable, said Le Fang, chief executive of CYT. Equipped with a UAV code identification management system, the electromagnetic shield can also track drone controllers, he added.

With the development of the general aviation market and the quick spread of UAVs, drone intrusions into flight-restricted areas have become frequent, said Le.

China has more than 20,000 drones, but half of their operators lack licenses, meaning their craft are 'flying black' -- a term for unauthorized UAV flights -- per figures compiled late last year by Ke Yubao, executive secretary-general of the Aircraft Owners and Pilots Association of China.

The global anti-drone market will grow at an annual rate of 24 percent between now and 2022 and is set to reach USD1.14 billion by 2022, according to a report published by market research firm MarketsandMarkets in February.
