The Defense Systems Information Analysis Center (DSIAC) was recently tasked with finding sensors capable of detecting large objects (∼20 ft × 10 ft × 10 ft or greater in volume) inside an open field. This sensor must not give off a visual signature to the naked eye or low-light visual detection tools or give off radio frequency emissions. It must function in complete darkness (i.e., no sun, moon, starlight, etc.).

The sensor must meet the following criteria:  maximum of 365 mm long, 156 mm wide, 110 mm high, and weigh less than 6 lb, including the mounting brackets or any other mounting and stabilizing necessities (ideal weight is less than 3.65 lb). It must also function between -20 °C and 45 °C; have an average power draw of less than 33 W, maximum average power draw no greater than 54 W, and an ingress protection value of 64 (IP64) or greater; and withstand the vibration environment in the sensor’s location while its natural frequencies avoid critical excitation frequencies of 14.7 Hz and 44 Hz.

Potential communication interfaces include serial RS-232 connection, gigabit Ethernet connection, 10/100 Ethernet port, or 1pps output to payload. Power voltage rails of 28 VDC (2A or 3A max), 12 VDC (2A or 3A max), or 5 VDC (×2, 2A max each) are available.

If you have any information, expertise, research publications, or know of relevant key contacts, please fill out the Active Inquiry form here and reach out to Olutoye Sekiteri (Olutoye.sekiteri.ctr@mail.mil), the lead IAC analyst for this effort, by clicking the “Collaborate with Us” or “Join the Discussion” buttons below.
