SIRE Radar

rdf:langString SIRE Radar

rdf:langString The Synchronous Impulse Reconstruction (SIRE) radar is a multiple-input, multiple-output (MIMO) radar system designed to detect landmines and improvised explosive devices (IEDs). It consists of a low frequency, impulse-based ultra-wideband (UWB) radar that uses 16 receivers with 2 transmitters at the ends of the 2 meter-wide receive array that send alternating, orthogonal waveforms into the ground and return signals reflected from targets in a given area. The SIRE radar system comes mounted on top of a vehicle and receives signals that form images that uncover up to 33 meters in the direction that the transmitters are facing. It is able to collect and process data as part of an affordable and lightweight package due to slow (40 MHz) yet inexpensive analog-to-digital (A/D) converters that sample the wide bandwidth of radar signals. It uses a GPS and Augmented Reality (AR) technology in conjunction with camera to create a live video stream with a more comprehensive visual display of the targets. The SIRE radar is part of a long generation of UWB and synthetic aperture radar (SAR) systems developed by the U.S. Army Research Laboratory (ARL) starting in the early 1990s. Past systems include the railSAR and the boomSAR systems as well as the more recent Spectrally Agile Frequency-Incrementing Reconfigurable (SAFIRE) radar system. The SIRE radar was eventually transitioned to the Communications Electronics Research, Development and Engineering Center (CERDEC) at Fort Belvoir, VA. There, it was redesigned as the ALARIC radar system, which was modified to have one fewer transmitter and operate at a bandwidth range from 100 MHz to 1.5 GHz.
