While there exists a wide variety of radar absorbing material (RAM) composites that can prevent the detection of shelters and vehicles, there are currently no effective and lightweight wearable options to mitigate GSR detection of a dismounted soldier.

The US Army is looking into methods that enable even the clothes soldiers wear fit into the complex future battlefield. A research solicitation published by the Army recently looks for industry answers on how to shield troops from ground radar that is capable of “large area monitoring.”

The technology they’re seeking would basically absorb or shield the signature of the individual soldier from those radar surveillance devices. Those devices leave a soldier vulnerable to detection. While in the past some of the radar technology was expensive and bulky, advances have brought such systems down to an affordable and transportable level for all manner of adversaries.

It’s all part of the larger multi-service-wide effort to fight in the electromagnetic spectrum, which includes stronger signaling for communications and targeting and jamming opponent signals.

Some of the tech is out there for larger items like tents and trucks. This posting aims to put it on the soldiers themselves.

Whichever companies come up with solutions to present to the Army must first provide prototypes for both lab and field testing. Those will be able to be applied to equipment such as uniforms, body armor, helmets or rucksacks, for example.

The material will then be tested for shielding or absorbing emissions for radar detection at up to 12-kilometer distances.

It must operate where the Army does, from -30 degrees F to 125 degrees F and in high humidity, rain or other challenging weather conditions.

The final product, if tested successfully, could entirely replace current textiles being used in those applications or integrated into existing materials that are already being worn by soldiers, and likely would be followed by ground combat units in other services.
