The Advantages and Disadvantages of Using tethered Aerostats

The Tethered Aerostat Radar System, otherwise known as the ELF-Band deployed aerial thermal imaging system is an American low-altitude airborne thermal imaging system which uses tethered aerostats as radars. Other similar systems available on the market include the EL/M-2083, an upgrade to the original JLENS system and the newest model of the ELF-Band. These radars are most commonly used for “area awareness” during exercises such as exercises simulating Desert Shield or similar operations in Middle East, but they have also been used in situations such as locating a boat under water or at high risk points on bridges. Such systems use either infra-red (infrared) or radar technologies. Click Here –

What Are Tethered Aerostats?

The primary advantage of using tethered aerostats for tracking and monitoring is the large area they can cover, covering large areas in a relatively short time. The ability to scan large areas quickly is one of the main advantages of using these sensors. Another main advantage is that these systems do not require the same maintenance that other airborne sensors would need to remain weatherproof. Since the devices are not tethered to the aircraft, there is a very low possibility of them becoming damaged by high winds or icing. They are also more resistant to vandalism and other abuse than other airborne sensors.

The third main advantage when compared to other airborne mass sensors is that these devices have a much smaller range. This means smaller maps to scan and therefore less preliminary processing of data to be returned. However, most applications will see a much greater range when compared to traditional radar gun mounted mobile systems. Also, with the many variants of the ELF-band, a wide-area tracking capability is achievable. Some common configurations of this kind include low-volume scan capabilities with a maximum payload of around one thousand pounds, medium-volume scan capabilities of up to ten thousand pounds, and high-volume scan capabilities of up to thirty-five hundred pounds.
