Abstract:

MIT Lincoln Laboratory has recently completed a development effort known as the Wideband 
Networked Sensors (WNS) project. The goal of this DARPA-funded project was to demonstrate 
a communication-intensive military application—remote real-time radar imaging of complex 
satellites and sensor fusion—using the BoSSNET test bed, an all-optical wide-area network 
that connects Boston and Washington, D.C.
The X-band Haystack Long-Range Imaging Radar (LRIR) and Ku-band Haystack Auxiliary Radar 
(HAX) located in Tyngsboro, Massachusetts, were connected via a sixty-mile-long fiber 
network to a remote processing center located at MIT Lincoln Laboratory in Lexington, MA. 
Unprocessed radar data (I&Q) was transmitted through the network to the center, where 
data from the two bands was fused and ultra-wideband images were generated in real time 
and displayed. The images were sent to the BoSSNET and looped back to simulate its 
capability to support a wideband communication long-distance link. 
The remote real-time imaging system consisted of three separate processing pipelines: one 
image stream per radar and one for the virtual ultra-wideband radar to demonstrate the 
Sparse Band Fusion processing. The complex processing of the individual radars’ data was 
accomplished in real time, while the fused ultra-wideband images were processed in real 
time and near-real time.
This paper will discuss the development effort, system configuration, and processing software, 
and highlight some recent remote real-time imaging demonstrations.
