The "BZ" series of electronic countermeasure jammers are mounted on air target platforms to simulate combat modes such as enemy support jamming, team jamming, and self-defense jamming, and provide targets close to the actual combat background for the army's radar test and training. This type of jammer is small in size and light in weight, and can carry a variety of target drones, airships, helicopters, unmanned helicopters and unmanned rotorcraft platforms.
