Helmet Mounted Radar System (HRMS)

The Helios Remote Sensing Systems team will develop a miniature, low power, 360-degree field of view Moving Target Indicator (MTI) radar sensor that will alert the soldier to the whereabouts of targets out to at least 25 meters with a goal of 50 meters while operating in harsh environments. The sensor will be mounted, embedded, and integrated within the Advanced Combat Helmet and associated sensor suites. Special attention has been paid to system weight, power consumption, and health of the soldier for this application. The total weight of the system is projected to be less than 2 ½ pounds with less than one pound mounted on the helmet. Several options will be investigated as a means to cue the soldier to the whereabouts of the targets. Special waveforms are considered for tag interrogation to enable precise location of blue forces, as well as target discrimination. Detection of small arms fire is included as part of the trade study. The compact, low cost, low-power radar will employ a novel 360 degree field of view helmet mounted antenna, novel signal, clutter and motion compensation processing algorithms and state-of-the-art chip-based implementations to optimize performance and low power operation.
