On December 27, the U.S. Army posted a request for information on Multi-Domain Operations Support Equipment. Responses are due by 4:30 p.m. Central on January 27.
Multi-Domain Operations (MDO) Support Equipment are payload systems and sensors to be integrated onto MQ-1C Gray Eagle UAS to penetrate defense-in-depth anti-access and area denial (A2AD) environments, sense, identify and geolocate enemy threat radar and communication systems that are encompassed in the Integrated Air Defense Systems (IADS). The MDO Support Equipment will include capabilities to detect, identify, locate, report and share information on enemy threats. The MDO Support Equipment will be payloads on the MQ-1C Gray Eagle UAS having software and hardware that will be common, open, modular and scalable. Integration of MDO Support Equipment onto the MQ-1C Gray Eagle UAS operating above 20,000ft AGL is a near-term demonstration goal for the US Army UAS Product Manager MAE. The MDO Support Equipment are systems that are already Technology Readiness Level (TRL) 6 or greater, suitable for integration onto the MQ-1C Gray Eagle and demonstration in an operational environment within 18 months. The MDO Support Equipment will include the following capabilities:
Radar Warning Receiver (RWR) / Electronic Support Measures (ESM) are payload systems that detect and identify Low Probability of Detection (LPI) emissions from threat radar systems, perform direction finding (Angle of Arrival) and precision geolocation, to provide tactical situational awareness to battlefield commanders through a digital data link and support cueing of Air Launched Effects (ALE) and Precision Fires. For the MDO Support Equipment, RWR/ESM systems will have wide instantaneous bandwidth (up to 2 GHz) to increase probability of detection and minimize time to correct ID of modern radar threats. The RWR/ESM systems will detect and correctly ID a very large set of threats (and associated modes) over the frequency range 0.5 to 40 GHz, using dual-polarized direction finding apertures. As an objective, the RWR/ESM systems will provide the capability to detect and correctly ID modern frequency-agile radar threats that employ frequency hopping techniques up to 2 GHz, changing modulation pulse-to-pulse, and modulation techniques such as Frequency Modulation on Pulse (FMOP), Phase Modulation on Pulse (PMOP) and mono-pulse.
Electronic Intelligence (ELINT) are payload systems that detect, analyze and record radiations from LPI tactical radars and tactical Electronic Warfare (EW) threat systems. For the MDO Support Equipment, the ELINT systems will operate on electromagnetic signal over the frequency range 0.5 to 40 GHz. The ELINT systems will perform direction finding, precision geolocation, and raw signal data recording functions. The ELINT systems will have local storage to support file transfer, with the objective to have on-aircraft analysis capability.
Synthetic Aperture RADAR (SAR) / Moving Target Indicator (MTI) are payload systems that provide increased situational awareness through wide area surveillance, imaging of stationary targets, and detection of moving targets. The SAR/MTI payload is capable of on-board processing and transmission of near-real-time imagery and moving target detection data to battlefield commanders through a digital data link. For the MDO Support Equipment, the SAR/MTI systems will provide the capability to image stationary targets at distances up to 60 Kilometers from the aircraft, with a sufficient resolution to perform target and threat identification.
When integrated on the MQ-1C Gray Eagle UAS, the RWR/ESM, ELINT and SAR/MTI systems will be interoperable with each other and electromagnetically compatible with other avionics and sensors on the MQ-1C Gray Eagle UAS.
